Reactive oligomers and polymers: Synthesis and application for polymer modification

摘要: The classification of reactive oligomers and some aspects their reactivity in crosslinking systems is discussed, related to three experimental attemps contribute a better understanding epoxy network modification by polymers. The synthesis telechelic with functional groups at the chain end as starting materials for modified epoxies proved be successful only when all mechanisms occurring below gel point had been investigated model reactions on one hand and, other, actual determination influence structure established. Ethylene-vinylalcohol copolymers controllable amount hydroxylic are convenient system. reaction OH-groups acid anhydrides produces carboxylic attached onto polymer which useful hardeners resins. more complex than might expected. More information now available about oligoether sequences prepared anionically cationically induced glycidyl ethers. Using compounds, several different types have found depend initiating agent.
