Beschreibung
Zusammenfassung:	A composition includes one or more copolymers of one or more vinylidene aromatic monomers and one or more unsaturated compounds containing nucleophilic groups, and the copolymer has on average about 0.01 to about 15.0 percent by weight of nucleophilic groups pendant from the copolymer. The copolymer is chain extended and/or branched by one or more copolymers of one or more vinylidene aromatic monomers and one or more unsaturated compounds having electrophilic groups, or a portion of the chains of the copolymer of one or more vinylidene aromatic monomers and one or more nucleophilic groups are crosslinked with other chains of the copolymer of one or more vinylidene aromatic monomers and one or more nucleophilic groups by ionic bonding of anions formed from the pendant nucleophilic groups with a metal cation having a valence of 2 or greater or complexation between pendant acid groups and metal oxides.
