Abstract
A high strength, thermally resistant, fire retardant, composition of matter is provided comprising (A) about 99.5 to about 75 weight percent of unmodified polymethylpentene where the weight percent of polymethylpentene is based on the total weight of A and B; and (B) about 0.5 to about 25 weight percent of polyphenylene sulfide where the weight percent of polyphenylene sulfide is based on the total weight of A, and B; (C) about 10 to about 67 weight percent of a reinforcer where the weight percent of the reinforcer is based on the total weight of A, B, C, and D; (D) optionally about 5 to about 45 weight percent of a flame retardant where the weight percent of the flame retardant is based on the total weight A, B, C and D.
Claims10
A composition of matter consisting essentially of:
- about 99.5 to about 75 weight percent of composition (a), wherein the weight percent of composition (a) is based on the total weight of compositions (a) and (b), and wherein composition (a) consists essentially of unmodified polymethylpentene;
- and
- about 0.5 to about 25 weight percent of composition (b), wherein the weight percent of composition (b) is based on the total weight of compositions (a) and (b), and wherein composition (b) consists essentially of polyphenylene sulfide;
- and
- about 10 to about 67 weight percent of composition (c), wherein the weight percent of composition (c) is based on the total weight of compositions (a), (b), and (c), and wherein composition (c) consists essentially of glass fibers;
- and
- wherein composition (a), composition (b), and composition (c) are compounded at a temperature above the melting point of said unmodified polymethylpentene and said polyphenylene sulfide.
A composition of matter consisting essentially of:
- about 99.5 to about 75 weight percent of composition (a), wherein the weight percent of composition (a) is based on the total weight of compositions (a) and (b), and wherein composition (a) consists essentially of unmodified polymethylpentene;
- and
- about 0.5 to about 25 weight percent of composition (b), wherein the weight percent of composition (b) is based on the total weight of compositions (a) and (b), and wherein composition (b) consists essentially of polyphenylene sulfide;
- and
- about 10 to about 67 weight percent of composition (c), wherein the weight percent of composition (c) is based on the total weight of compositions (a), (b), (c), and (d), and wherein composition (c) consists essentially of glass fibers;
- and
- about 5 to about 45 weight percent of composition (d), wherein the weight percent of composition (d) is based on the total weight of compositions (a), (b), (c), and (d), and wherein composition (d) consists essentially of flame retardants;
- and
- wherein at least composition (a), composition (b), and composition (c) are compounded at a temperature above the melting point of said unmodified polymethylpentene and said polyphenylene sulfide.
