Dataset in characterization of the polymer produced using different method of synthesis polychloromethylstyrene (PCMS) with clay and without clay

Polychloropolymethylstyrene (PCMS) polymers were synthesized with clay Cloisite and without clay Cloisite and chloromethylstyrene (CMS) combine with styrene (1:1) v/v or known as copolymer and clay Cloisite by the polymerization process. The attenuated total reflection-Fourier transform infrared (ATR-FTIR) spectra of each polymer synthesized are reported. The spectra of IR shows the different value of the wavenumber and intensity for each set of different sample. The spectra can be as a reference for others to use in synthesizing this polymer and clay Cloisite for different type of application.

Value of the Data
• It is important to make superior/versatile polychloromethylstyrene (PCMS) polymer that has enhanced properties once cast as a film making the film more stable, more temperature resistance, and increasing the shelf life of the polymer. • The researcher might use this data to form a polymer and clay film with a particular type of clay and its ratio. • The researcher can use data to compare and design the experiment involving polymers such as CMS with clays. • Data can be useful in producing different types of polymer derivatives or modifications using starting material CMS. This modified polymer can anchor or attract any desired compounds or target materials for further use.

Data Description
The dataset contains FTIR data of the polymer synthesized with a different combination of clay and its ratio. The monomer of chloromethylstyrene (CMS) was synthesized with and without combine with clay Cloisite. Clays and their modified forms have received significant interest for their use as adsorbents of metal ions from aqueous medium due to readily available and much cheaper than activated carbon, zeolites, and membranes [1] . The monomer of CMS was also synthesized with styrene with and without the presence of clay. Three different types of clay Cloisite were used which are 10A, 15A and 20A. Clay Cloisite is organically modified layered magnesium aluminum silicate platelets. 10A, 15A and 20A referred to the modifier (intercalatant) applied in the modification of montmorillonite (MMT). To observe which combination is better with the variation of the ratio of clay, these polymers were characterized using ATR-FTIR. Based on Table 1 , the FTIR spectra of CMS without clay Cloisite and CMS with clay Cloisite 10A, 15A and 20A with different percentage of clay Cloisite used. This article provides experimental data of characterization of each of CMS synthesized. The different ratios used and different types of clay also used presence.

Infrared spectroscopy
Fourier Transform Infrared Spectrophotometer IR Tracer-100 Solution Shimadzu was used to perform attenuated total reflectance Fourier transform infrared spectroscopy (ATR-FTIR). The number of scans is 40 scans which scan at 40 0 0 to 400 cm −1 wavenumbers. The band positions were obtained using the IR Tracer Software.

Data FTIR
Synthesis of CMS without clay Cloisite : Synthesis of polymer without solvent called (Homopolymerization) . 15 mL of CMS was mix with 0.5% NaOH (w/v) to remove inhibitor from the monomer and repeat three times. The monomer was washed with deionized water until the water becomes neutral after removed the inhibitor. To remove the excess water, potassium carbonate was added to the monomer. Heat the monomer at the temperature of 85 °C with a stirring speed of 150 rpm in nitrogen condition. The CMS was heated until completely viscous. The viscosity of the solution will change from runny-like water to honey-like viscosity. After viscous, MEK was dropped in the viscous solution and the mixture was dropped added slowly to the volume of 20 mL in the beaker that contained methanol to obtain the polymer flakes. The flakes were then filtered using a Buchner funnel and dried for 10 minutes in the oven [2] . ATR -FTIR; 3021, 2924, 2346, 1909, 1605, 1513, 1439,1418, 1264, 911, 825, 672 cm −1 .

Synthesis of polymer with clay Cloisite
The 15 mL CMS was removed the inhibitor first by adding 15 mL of 0.5% NaOH in the separating funnel and repeat for three times. Then, the deionized water was added in the separating funnel to wash the remaining NaOH. Sodium carbonate was added to remove excess water. An amount of clay Cloisite was added according to the percentage of clay needed into a flat bottom flask containing CMS. It was heated in an oil bath with a temperature under 85 °C with a stirring speed of 150 rpm in nitrogen condition. The CMS was heated until completely viscous. The viscosity of the solution will change from runny-like water to honey-like viscosity. After viscous, MEK was dropped in the viscous solution and the mixture was dropped added slowly to the volume of 20 mL in the beaker that contained methanol to obtain the polymer flakes. The flakes were then filtered using Buchner funnel and dried for 10 minutes in the oven.

Synthesis of polymer and copolymer with clay Cloisite
15 mL of 0.5% NaOH was added to 15 mL CMS in separating funnel to remove inhibitor from CMS and 15 mL of 2.5% NaOH was added to 15 mL styrene and repeat three times to remove inhibitor. Then, the deionized water was added in the separating funnel to wash the remaining NaOH. Sodium carbonate was added to remove excess water. An amount of clay Cloisite was added according to the percentage of clay needed into flat bottom flask containing CMS. It was heated in an oil bath with a temperature of under 85 °C with a stirring speed of 150 rpm in nitrogen condition. The CMS was heated until completely viscous. The viscosity of the solution will change from runny-like water to honey-like viscosity. After viscous, MEK was dropped in the viscous solution and the mixture was dropped added slowly to the volume of 50 mL in the beaker that contained methanol to obtain the polymer flakes. The flakes were then filtered using Buchner funnel and dried for 10 minutes in the oven.

Formation of film CMS and clay Cloisite 10A 4%
The 4% (w/v) of the clay Cloisite 10A and CMS were synthesized as mentioned above. After synthesized, the polymer flakes formed will be dissolved with DMF and were cast on the glass. After cast for 5 hours, the fil was cured in the oven for 5 hours. The functionalization was proceeded by heating the film in (N, N-dimethylhexadecylamine:1,4-dioxane) (6:4), crosslinked with (N, N-dimethylhexadecylamine: 1,6-diaminohexane) (6:4) and diethanolamine for 5 hours each.
