wherein Z is an aromatic group, each R is individually selected from the group consisting of alkyl groups of from 1 to about 12 carbon atoms, thioalkyl groups of from 1 to about 12 carbon atoms, and halogen atoms, n is from 1 to about 6, and x is from O to 7, are suitable for use in preparing rubber latex particles. The rubbers are useful as substrates in graft copolymers and the resulting graft copolymers are suitable for use in thermoplastic blend compositions, particularly with transparent polymers. The rubber material. are advantageous in that they exhibit low glass transition temperatures and high refractive indices.
摘要:
A reduced fogging impact modified vinyl chloride composition is provided. The composition contains a graft copolymer which is formed by an emulsion process involving grafting a rigid polymeric superstrate to a polyacid surfactant containing rubber. The composition is useful for making molded parts such as automotive dash components, and exhibit reduced level of fogging onto the automotive windshield compared to graft copolymers formed via a process utilizing a linear mono fatty acid.
摘要:
The present invention involves blends of polycarbonate resin with rubber grafted terpolymer resin, one or more styrenic rigid coplymers wherein a small amount of an aliphatic C 4 to C 16 polyalpha olefin homopolymer or copolymer or its functionalized derivatives is included in the blend.

摘要:
A flame retardant high impact polystyrene composition is provided comprising (a) a high impact polystyrene, (b) a block copolymer of polystyrene and polybutadiene, (c) a halogenated flame retardant, (d) a metal synergist, and (e) a polytetrafluoroethylene polymer. The compositions exhibit V-O flame retardancy at relatively low halogen flame retardant levels and exhibit relatively low melt flows compared to higher loading levels of halogen flame retardants. The compositions are useful for making molded articles such as business machine housings.
摘要:
Low juicing impact modified thermoplastic compositions and injection molding processes using the thermoplastic compositions. The thermoplastic compositions utilize as modifier an emulsion graft copolymer made using a latex emulsified with a polyacid. The compositions exhibit reduced tendencies to juice (plate out) during injection molding thereof. The compositions are useful in making impact strength enhanced thermoplastic articles.
