Definition

Dendrimers are repetitively branched macromolecules having perfect fractal structure. Hyperbranched polymers, on the other hand, are imperfect architectural relatives of dendrimers. Due to synthetic challenge in forming unsymmetrical carbon–carbon bonds, purely aliphatic hydrocarbon dendrimers have not been reported in literature. Hyperbranched polyolefins refer to olefin polymers having hyperbranched architecture that are formed by addition polymerization of olefinic monomers [1]. Dendritic polyolefins specifically refer to hyperbranched polyolefins that have more globular structure closely resembling dendrimers.

Historical Background

Polyolefins are an important category of synthetic materials with millions of tons produced annually for broad applications including fibers, plastics, and elastomers. One critical molecular...
