Abstract
The invention relates to improved polymer material blends which include the compatibilizing agent, a compound of phosphoroustrislactams which is useful as a compatibilizing agent, between the polymer materials. An exemplary composition comprises one or more polyphenylene oxides, one or more polyesters and the compatibilizing agent comprising phosphoroustrislactams.
Claims19
A composition comprising:
- a poly(Phenylene ether);
- a polyester;
- and a phosphoroustrislactam.
A blend comprising at least one poly(phenylene ether) and at least one Polyester which further includes at least one phosphoroustrislactam as a compatibilizing agent.
A compatibilized blend comprising the constituents of:
- (A) at least one Poly(Phenylene ether)
- (B) at least one polyester, and
- (C) at least one phosphoroustrislactam as a compatibilizing agent where the compatibilized blend of (A), (B) and (C) exhibits a tensile strength which is in excess of the tensile strength of only the constituents (A) and (B).
A compatibilized blend of at least one Poly(Phenylene ether) and Poly(ethylene terephthalate) which further includes at least one phosphoroustrislactam as a compatibilizing agent which exhibits a tensile strength which is in excess of the tensile strength of the at least one poly(phenylene ether) and the poly(ethylene terephthalate) without phosphoroustrislactam.
