1. A composition comprising one or more copolymers of one or more vinylidene aromatic monomers and one or more unsaturated compounds containing nucleophilic groups, the copolymer having on average about 0.01 to about 15.0 percent by weight of nucleophilic groups pendant from the copolymer, wherein;
a) 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,
b) 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 i) ionic bonding of anions formed from the pendant nucleophilic groups with a metal cation having a valence of 2 or greater or ii) complexation between pendant nucleophilic groups and metal oxides;
wherein the composition contains a rubber based impact modifier; and,
has a Mz+1 of about 600,000 to about 2,500,00 measured by gel permeation chromatography (GPC) and a gel content of 30 or higher measured as described in the description.
