✦ Synopsis

Graft copolymers of functionalized polyethylene having free carboxylic groups/PEox/and liquid crystalline polyester SBH derived from sebacic acid, 4,4'-dihydroxybiphenyl and 4-hydroxybenzoic acid, prepared in various conditions, as well as fractionation products of the graft copolymers, were investigated by infra-red spectroscopy. The grafting has been followed by changes in the amount of carboxylic and aliphatic-aromatic ester groups.
