    摘要： Disclosed are such co-polymers of vinylidene substituted aromatic monomers and unsaturated compounds containing nucleophilic groups chain extended by a copolymer of one or more vinylidene aromatic monomers and one or more unsaturated compounds having pendant electrophilic groups which copolymerize with the one or more vinylidene aromatic monomers. Disclosed are compositions comprising vinylidene substituted aromatic monomers and unsaturated compounds containing nucleophilic groups and a copolymer of one or more vinylidene aromatic monomers and one or more unsaturated compounds having pendant electrophilic groups, which may optionally, contain salts of alkaline earth metals, alkali metals, transition metals, post transition metals or metalloids. Disclosed are methods of preparing such chain-extended and/or branched copolymers.

    摘要： A composition comprising: one or more polycarbonates; one or more vinylidene aromatic substituted polymers; and a buffer system that controls the pH in water at 25° C. at a value of about 6.0 to about 8.0. The composition may comprise the buffer system that has a pKa between about 4 and about 10. The composition may comprise: from about 10 or 50 to about 95 percent by weight of the one or more polycarbonates; from about 0.5 or about 10 to about 50 or about 90 percent by weight of the one or more vinylidene aromatic substituted monomers; and from about 0.005 percent to about 0.050 percent by weight of the buffer system; wherein weight is based on the total weight of the composition. The buffer system may be present in an amount from about 0.010 percent to about 0.040 percent by weight.

    摘要： Disclosed are nitrile-vinylidene substituted aromatic polymers which include less than about 250 ppm of vinylidene substituted aromatic monomer. Also disclosed is a method of minimizing nitrile migration in nitrile-vinylidene substituted aromatic polymers where the amount of residual vinylidene substituted aromatic monomer in the nitrile-vinylidene substituted aromatic polymer is reduced. Also disclosed is a method of making nitrile-vinylidene substituted aromatic polymers which includes less than about 250 ppm of styrene monomer.

    摘要： Disclosed are ionomers of co-polymers of vinylidene substituted aromatic monomers and unsaturated compounds containing acid groups crosslinked by the residue of one or more metal salts and/or metal oxides of a metal having a valence of 2 or greater. The crosslinks are reversible and the weight average molecular weight of the copolymer of one or more vinylidene aromatic monomers and one or more unsaturated acids may be substantially the same after the crosslinking is reversed as it is before crosslinking. A portion of the chains of the copolymer of one or more vinylidene aromatic monomers and one or more unsaturated acids are crosslinked with other chains of the copolymer of one or more vinylidene aromatic monomers and one or more unsaturated acids. Disclosed are methods of preparing such ionomers

    摘要： A foaming composition useful to make an extruded foam is comprised of: a copolymer of a vinylidene aromatic monomer and an unsaturated compound containing nucleophilic groups, a copolymer of vinylidene aromatic monomer and an unsaturated compound having electrophilic groups; and a blowing agent. The foaming composition may be made into a foam by heating the foaming composition to a temperature sufficient to melt and react said copolymers to form a chain extended/branched copolymer and extruding the foaming composition from a higher pressure to a lower pressure to form an extruded foam comprised of the chain extended/branched copolymer. The foam is comprised of a chain extended/branched copolymer that is the reaction product of (i) a copolymer of one or more vinylidene aromatic monomers and one or more unsaturated compounds containing nucleophilic groups, and (ii) a copolymer of one or more vinylidene aromatic monomers and one or more unsaturated compounds having electrophilic groups.

    摘要： A foaming composition useful to make an extruded foam is comprised of comprising a plurality of chains of a copolymer of one or more vinylidene aromatic monomers and one or more unsaturated acids, the copolymer having about 0.01 to about 15.0 percent by weight of the one or more unsaturated acids wherein the acid groups are pendant from the copolymer a metal salt, metal oxide or combination thereof, the metal having a valence of at least 2; and one or more blowing agents. The foaming composition may be made into a foam by heating the foaming composition to a temperature sufficient to melt and ionically crosslink said copolymer which is then extruded through a die forming a foam. The foam is comprised of an ionically crosslinked aforementioned copolymer, wherein the copolymer is crosslinked through ionic bonds between the unsaturated acids and the metal of the metal salt or metal oxide.
