Abstract
Thermoplastic resin alloys containing polyphenylene sulfide resin and at least one other thermoplastic resin selected from the group consisting of polyarylsulfones, polyphenylene oxides, and polyarylcarbonates are disclosed which have certain physical properties that are better than those of at least one of the resins employed in preparing the alloy. Also, specific polyphenylene sulfide/polyarylsulfone alloy compositions are disclosed which have certain physical properties that are better than those of either the polyphenylene sulfide or the polyarylsulfone employed.
Claims25
A unitary thermoplastic mass comprising polyphenylene sulfide and at least one other thermoplastic resin selected from the group consisting of polyarylsulfones, polyarylcarbonates, and polyphenylene oxides.
A method of forming a polyphenylene sulfide containing alloy which has higher impact resistance than the polyphenylene sulfide employed comprising forming an alloy of polyphenylene sulfide and an amount of at least one non-polyphenylene sulfide thermoplastic, selected from the group consisting of a polyarylsulfone derived from 2,2-bis(4-hydroxyphenyl)propane, a polyarylcarbonate derived from 2,2-bis(4-hydroxyphenyl)propane, or a polyphenylene oxide derived from a 2,6 di-methyl substituted phenol sufficient to insure that the resulting composition has an impact resistance greater than that possessed by the polyarylene sulfide.
An insulated wire in accordance with claim 22 wherein the polyarylsulfone comprises approximately 50 weight percent of the resin in the coating composition and the polyphenylene sulfide accounts for the remainder of the resin.
A method of forming a polyphenylene sulfide containing alloy that has at least one property that is better than that of at least one of the resins employed in preparing the alloy comprising forming an alloy of sufficient amounts of polyphenylene sulfide and at least one nonpolyphenylene sulfide thermoplastic selected from the group consisting of polyarylsulfones, polyarylcarbonates, and polyphenylene oxides.
