Development of Polymers Based on 1-Functionalized Benzocyclobutene-based Monomers with Controlled Curing Temperatures

摘要

Benzyocyclobutene(BCB)is important in polymer science for crosslinking reactions because the reaction is thermally activated and no small molecule byproduct is released Although the high thermal stability of BCB up to-200 °C is advantageous for synthesizing and processing engineering polymers at elevated temperatures,more energy efficient crosslinking at lower temperature would be advantageous for rubber compounding.The ring-opening isomerization temperature of BCBs can be lowered by introducing substituents at the benzylic position of the cyclobutene ring.This talk will present the development of 1-functionalized benzocylobutenes that crosslink by ring-opening isomerization at lower temperatures,and that are polymerizable through styrene and methacrylate groups.
