COMPOSITE COMPONENTS FROM POLYCARBONATE / POLYESTER COMPOSITIONS AND POLYURETHANE, HAVING IMPROVED INTERLAYER ADHESION
Document Type and Number:
WIPO Patent Application WO/2011/070044
Kind Code:
A4
Abstract:
The invention relates to composite components which comprise a) a substrate from a thermoplastic composition containing A) at least one polymer selected from the group of the aromatic polyester carbonates and aromatic polyesters in a proportion of [A] of 20.0 to 85.0 parts by weight, based on the sum of components A and B, B) at least one rubber-modified vinyl(co)polymer in a proportion of [B] of 15.0 to 80.0 parts by weight, based on the sum of components A and B, having a rubber content [KB] of at least 25.0 parts by weight, based on component B, and C) at least one polymer additive in a proportion of [C] of 0 to 30.0 parts by weight, based on the sum of components A and B, and b) at least one polyurethane layer, the thermoplastic composition being characterized by an overall rubber content, based on the sum of components A and B, of at least 12 parts by weight.
