Abstract

The synthesis of a series of comb shaped copolymers of poly(alkylene glycols) of various molecular weights and poly(methylhydrogen siloxane) is discussed. The grafting of the side chains renders the siloxane water soluble, although surface active. Uses investigated for these copolymers include their application as solid polymer-electrolytes, after complexation with Li** plus salts, and as novel high molecular weight protective solutes in current efforts to preserve tissue by vitrification. With the latter application in mind the low temperature phase behaviour of the copolymers in aqueous solution has been investigated. This has shown that the copolymers have similar ice nucleation inhibiting properties as the straight chain poly(ethylene glycols) of similar molecular weight and that the solutions become glass forming at about 40 wt% copolymer.
