Claims16
A composition comprising a polyolefin, polycarbonate and a compatibiliser, wherein said compatibiliser is a block copolymer comprising a polyolefin part and a polyester part, said polyester part having an average M/F ratio ≥2 and ≤25, wherein M is the number of backbone carbon atoms in the polyester not including the carbonyl carbons and F is the number of ester groups in the polyester,
- wherein the compatibiliser is a BAB type block copolymer with A representing polyolefin and B representing polyester.
A composition comprising:
- a very low density polyethylene, linear low density polyethylene, low density polyethylene, or a mixture of any of the foregoing polyethylenes,
- polycarbonate, and
- a compatibiliser, wherein said compatibiliser is a block copolymer comprising
- a polyolefin part comprising an ethylene copolymer containing at least 90 wt. % of ethylene on the basis of the weight of the polyethylene block, and
- a polyester part having an average M/F ratio ≥2 and ≤25, wherein M is the number of backbone carbon atoms in the polyester not including the carbonyl carbons and F is the number of ester groups in the polyester.
