Abstract
A blended composition containing polycarbonate, polyester, an olefinic epoxide-containing copolymer and a polyamine compound, which composition possesses a desirable balance of impact resistance, solvent resistance, and resistance to thermal deformation.
Claims14
A thermoplastic composition of matter comprising, in admixture,
- (a) polycarbonate,
- (b) polyester,
- (c) an olefinic epoxide-containing copolymer, having a glass transition temperature of less than 0.degree. C., prepared from (i) one or more olefin monomers, one or more conjugated dienes, or a mixture thereof, and (ii) at least one vinyl monomer carrying at least one epoxide ring, and
- (d) a polyamine compound.
The composition of claim 1 wherein the polyamine compound is described as
- H(A)N--E--(O--E).sub.c !.sub.d --O.sub.d --G--(O--G).sub.c !.sub.e --N(A)H wherein A, E and G are as set forth in claim 6, c is 1 to 70, inclusive, and d and e are both 0 or 1, although d and e cannot both be 0.
The composition of claim 1 wherein the polyamine compound is described as H(A)N--Q--O--C(O)--Q--C(O)--O--Q!.sub.f --O--C(O)--Q--C(O)--O--Q--N(A)H wherein Q is independently in each instance E or G, as set forth in claim 6, and f is 0 to 70, inclusive.
A thermoplastic composition of matter comprising, in admixture,
- (a) polycarbonate in an amount of from about 5 to about 92 weight parts
- (b) polyester
- (c) olefinic epoxide-containing copolymer, having a glass transition temperature of less than 0.degree. C., prepared from (i) one or more olefin monomers, one or more conjugated dienes, or a mixture thereof, and (ii) at least one vinyl monomer carrying at least one epoxide ring, and
- (d) polyamine compound in an amount of from about 0.0005 to about 1.0 weight parts,
- said weight parts being based on the total composition.
