Claims5
A method for improving the thermal performance of polymethylpentene/polyethylene terephthalate blends said method comprising admixing with polymethylpentene:
- (a) an amount of polyethylene terephthalate in the range of about 15 to about 55 weight percent based on the weight of said polymethylpentene;
- (b) an amount of glass fiber in the range of about 10 weight percent to about 50 weight percent, based on the total weight of the composition;
- and
- (c) an amount of at least one carboxylated polyolefin in the range of about 1 weight percent to about 35 weight percent based on the weight of said polymethylpentene thereby providing a blend of glass, polymethylpentene, polyethylene terephthalate and carboxylated polyolefin.
