Abstract
A process is described for obtaining a chemical blend of a polyolefin with a poly(hydroxy carboxylic acid) by mixing poly(hydroxy carboxylic acid) with at least one polyolefin in the presence of a compatibilising compound having at least one polymerisable double bond and at least one electrophilic functional group. The invention also relates to the chemical blend obtainable according to this process, as well as the use of the compatibilising compound to obtain chemical blends of polyolefin with poly(hydroxy carboxylic acid).
