Claims7
A reinforced intercrystalline normally rigid thermoplastic molding composition comprising, in combination,
- a. at least one high molecular weight normally crystalline polyester resin which very rapidly crystallizes from the melt;
- b. at least one high molecular weight normally crystalline, normally amorphous or normally partially crystalline and partially amorphous polymer which polymer comprises a mixture of a polymerization product of an ethylenically unsaturated monomer and at least one difunctionally reactive compound which is polymerizable by oxidation, said polymer being present in the concentration range of from 1 to 99 parts by weight of (a) to 99 to 1 parts by weight of (b);
- and
- c. a reinforcing amount of a reinforcing filler for said combination.
A reinforced intercrystalline normally rigid thermoplastic molding composition comprising, in combination,
- a. a high molecular weight normally crystalline linear poly(alkylene terephthalate, isophthalate or mixed terephthalate and isophthalate), said alkylene groups containing from 3 to 10 carbon atoms;
- b. a high molecular weight poly(methyl methacrylate) in the concentration range of from 1 to 99 parts by weight of (a) to 99 to 1 parts by weight of (b);
- and
- c. reinforcing filamentous glass, in an amount of from about 1 to 80 percent by weight based on the weight of the combination.
A reinforced intercrystalline normally rigid thermoplatic molding composition comprising, in combination,
- a. a high molecular weight normally crystalline poly(alkylene terephthalate, isophthalate or mixed terephthalate and isophthalate), said alkylene groups containing from 3 to 10 carbon atoms;
- b. a high molecular weight normally crystalline wholly aromatic polyester, in the concentration range of from 1 to 99 parts by weight of (a) to 99 to 1 parts by weight of (b);
- and
- c. reinforcing filamentous glass, in an amount of from about 1 to about 80 percent by weight based on the weight of the combination.
A reinforced intercrystalline normally rigid thermoplastic molding composition which consists essentially of,
- a. a high molecular weight normally crystalline poly(1,4-butylene terephthalate) resin;
- b. poly(2,6-dimethyl-1,4-phenylene ether) resin or poly(2,6-dimethyl-1,4-phenylene ether) resin in combination with a polystyrene resin, in the concentration range of from 1 to 99 parts by weight of (a) to 99 to 1 parts by weight of (b);
- and
- c. reinforcing filamentous glass, in an amount of from about 1 to 80 percent by weight based on the weight of the combination.
