Novel (meth)acrylate monomers for ultrarapid polymerization and enhanced polymer properties

摘要

Ultraviolet light is known to be one of the most efficient methods to initiate polymeric reactions in the presence of a photonitiator. Photopolymerizations are advantageous because the chemistry of the materials can be tailored to design liquid monomers for ultrarapid polymerization into a solid polymer material. One way to achieve rapid photopolymerizations is to utilize multifunctional (meth)acrylate monomers, which form highly crosslinked polymers: however, these monomers typically do not achieve complete functional group conversion. Recently, Decker et al. developed novel monovinyl acrylate monomers that display polymerization kinetics that rival those of multifunctional acrylate monomers. These novel acrylate monomers incorporate secondary functionalities and end groups such as carbonates, carbonates, cyclic carbonates, and oxazolidones, which promote the increased polymerization kinetics of these monomers. In addition to the polymerization kinetics, these novel monovinyl monomers form crosslinked polymers, which are characterized by having high strength and high flexibility. Unfortunately, the exact mechanism or mechanisms responsible for the polymerization kinetics and crosslinking are not well understood.
