Abstract
Thermoplastic materials may be functionalized and then blended with polyamides to form compatible products which contain a copolymer of the functionalized material and the polyamide.
Claims9
A thermoplastic blend comprising the following, and reaction products thereof:
- (a) about 30% by weight to about 70% by weight of a thermoplastic polymer having recurring carbonate units in the main chain and end groups of the formula ##STR9## wherein R.sup.1 is a trivalent group selected from the group consisting of aliphatic chains containing about 2-20 carbon atoms and aromatic groups containing about 6-20 carbon atoms;
- and
- Y and Z are individually selected from the group consisting of hydroxy and alkoxy groups, wherein Y and Z taken together are oxygen;
- and
- (b) about 30% by weight to about 70% by weight of a polyamide.
