Abstract
Compositions are described that are blends of a grafted copolymer and a polyamide. Methods of making the blended compositions are also described. The grafted copolymers are the reaction product of (1) a first compound having both an aziridinyl group and a polymeric group with (2) a second polymeric material having an acidic group. Blending the grafted copolymer with the polyamide can be used, for example, to increase the cohesive strength of the grafted copolymer.
Claims20
A composition comprising:
- a) a grafted copolymer comprising a product of a reaction mixture comprising
- 1) a first compound of Formula (I)
- wherein
- each R1 is independently hydrogen or an alkyl;
- R2 is a divalent group comprising an alkylene, heteroalkylene, arylene, heteroarylene, or a combination thereof and optionally further comprising an oxy, carbonyl, carbonyloxy, carbonylimino, —NR3—, or a combination thereof;
- R3 is hydrogen or an alkyl;
- and
- Q is a first polymeric group comprising a polymerized product of a first monomer composition comprising at least one ethylenically unsaturated monomer;
- and
- 2) a second polymeric material having at least one acidic group;
- and
- b) a polyamide blended with the grafted copolymer, wherein the polyamide is selected 1) to have a melting temperature no greater than 200° C., 2) to be at least partially soluble in the composition at blending temperature, or 3) both 1) and 2).
