Abstract
Thermoplastic resins of the invention are reaction products of vinyl aromatic/vinyl phosphonic acid copolymers and amine-terminated polymers. The flexible products, which contain ammonium linkages, are surprisingly transparent, and are useful for packaging, as fire-retardant polymers or polymer additives, and as polymer compatibilizers.
Claims21
A thermoplastic resin composition comprising the reaction product of:
- (a) a copolymer of a vinyl aromatic monomer and a vinyl phosphonic acid monomer;
- and
- (b) an amine-terminated polymer having a glass-transition temperature less than about 0.degree. C. in an amount effective to impart flexibility to the resin;
- wherein the reaction product contains one or more ammonium linkages.
1 more element
A thermoplastic resin composition comprising the reaction product of:
- (a) a copolymer of styrene and a vinyl phosphonic acid monomer having the structure:
- ##STR3## in which A is selected from the group consisting of aryl and halogen-substituted aryl groups;
- and
- (b) an amine-terminated polymer having a glass-transition temperature less than about 0.degree. C. in an amount effective to impart flexibility to the resin;
- wherein the reaction product contains one or more ammonium linkages.
2 more elements
A transparent thermoplastic resin composition comprising the reaction product of:
- (a) a copolymer of styrene and 1-phenylvinyl-1-phosphonic acid;
- and
- (b) an amine-terminated polyether having a glass-transition temperature less than about 0.degree. C. in an amount within the range of about 30 to about 50 weight percent based on the amount of thermoplastic resin;
- wherein the reaction product contains one or more ammonium linkages.
