Abstract
Blends of biodegradable polymers of hydroxybutyric acid and polyolefines of improved properties are produced by incorporating a compatibilising agent which comprises a block copolymer in which at least half of the mass of one block is represented by alkyl side chains and at least half of the mass of another block is represented by side chains which comprise hydroxy acid residues.
