摘要:
A thermoplastic molding composition which comprises a blend of:(A) a copolymer having recurring units of a monoalkenyl aromatic monomer and recurring units of an .alpha.,.beta.-ethylenically unsaturated dicarboxylic anhydride N-substituted imide, and(B) a hydrogenated elastomeric block copolymer having at least one substantially completely hydrogenated diene polymer mid block and at least two monoalkenyl arene polymer end blocks in which at least a portion of the arene groups contained in the end blocks are substituted with at least one substituent selected from the group consisting of nitrol, cyano and trifluromethanesulfonyl.
摘要:
Polyblends of impact modified styrene/.alpha.,.beta.-unsaturated dicarboxylic anhydride or imide copolymers and polyamides are disclosed. The resulting molded articles exhibit excellent mechanical strength, resistance to chemicals, toughness and resistance to heat.
摘要:
A moldable polyblend comprising a physical mixture of from about 99 to about 1% by weight poly(arylene sulfide) with from about 1 to about 99% by weight of a copolymer containing recurring units of a vinyl aromatic monomer and recurring units of a maleimide monomer is disclosed.
摘要:
A polyblend comprising a thermoplastic polycarbonate and at least one copolymer selected from methylmethacrylate/N-phenylmaleimide and EPDM-g-methylmethacrylate/N-phenylmaleimide is disclosed. In one embodiment, the polyblend will comprise an acrylonitrile-butadiene-styrene resin and/or a rubber modified styrene maleic anhydride copolymer.
摘要:
An improved diester process is provided for preparing a polyarylate polymer which process comprises reacting at least one aromatic dicarboxylic acid and a diester derivative of a dihydric phenol and an ester-forming agent having no hydrogens alpha to a carbonyl group of the ester-forming agent. Polyarylates produced by the improved process of this invention have a low degree of coloration, melt stability and a low level of haze.
摘要:
Blends comprising from about 1 to about 99 percent by weight of a poly(aryl ether ketone co-carbonate) and from about 99 to about 1 percent by weight of a thermoplastic polymer selected from the group of a poly(aryl ether ketone), a poly(arylene sulfide), a poly(ether imide) or a poly(aryl ether).
摘要:
A polymer composition which contains a polycarbonate resin, a styrenic/maleimide/cyclic anhydride terpolymer, and an ethylene/propylene/nonconjugated diene terpolymer chemically grafted with either styrene/acrylonitrile copolymer, methylmethacrylate/N-phenylmaleimide copolymer or polymethylmethacrylate is disclosed. The composition exhibits excellent impact strength properties upon molding.
摘要:
A moldable composition produced by incorporating a macromonomer/alkyl acrylate/glycidyl methacrylate terpolymer into a blend of polycarbonate and a styrenic copolymer is disclosed. The macromonomer/alkyl acrylate/glycidyl methacrylate terpolymer is effective in enhancing the weld-line strength of the molded composition.
摘要:
[2,5,8,11]-tetraalkyl-[2,5,8,11]-tetracyano-cis-6a' carboxy, 12a' oxoacide-3,4:9,10 bisdiazobicyclooctane compounds are disclosed. In one embodiment, the compounds are capable of initiating free radical polymerization and are well suited for the preparation of polymers having block type structures.
