Abstract
Polymeric composition comprising a polyolefin and a diacid-diol aliphatic-aromatic copolyester with aromatic part consisting mainly of terephthalic acid or its derivatives, aliphatic part consisting of azelaic acid, sebacic acid and brassylic acid and diol C2-C13. Said copolyesters are particularly compatible with polyolefins, in particular with isotactic polypropylene, in the absence of compatibilising agents.
Claims21
