Oligomeric phosphites based on resorcinol derivatives-promising stabilisers for elastomer composites

摘要

An effective means of protecting polymers against different types of ageing and, consequently, of lengthening the service life of polymer articles is to introduce high molecular weight antiagers into the polymer composites (ref. 1). THe growing interest in oligomeric stabilisers is due to such advantages over low molecular weight stablisers as the absence of volatility and washing out by water and in a number of cases by organic solvents, good compatibility with polymers, lower toxicity, high hydrolytic stability, and stabilising effectiveness.
