摘要： Compositions useful as absorbents for organic liquids are disclosed. A diamine or polyamine is reacted with a polymeric resin that contains phosphonic acid groups to produce the absorbent compositions of the invention. Because the polymeric resin component can be combined with the amine either before or after combination with the organic liquid, the absorbents of the invention can be used in many forms. The polymeric resin component can be processed into any desired form (shaped article, solution), and the di- or polyamine can then be added to generate the absorbent in situ. Unlike spent absorbent compositions of the prior art, those of the invention can be converted to pumpable liquids by heating or by adding a gel-breaking agent to liquify the gel. A useful absorbent is recovered from the liquid by precipitation or distillation.

摘要： Flame-retardant, thermoplastic copolymers and processes for making them are disclosed. The compositions are copolymers of a vinyl aromatic monomer, a vinyl phosphonic acid derivative, and optionally, an unsaturated organic diacid, ester, or anhydride that are grafted onto a rubber. Processes for making polymers having high molecular weight, good mechanical properties, and a high level of evenly distributed, chemically incorporated vinyl phosphonate flame retardant are also disclosed.

摘要翻译：公开了可用作有机液体的吸收剂的组合物。二胺或多胺与含有膦酸基团的聚合物树脂反应以产生本发明的吸收剂组合物。因为聚合物树脂组分可以在与有机液体组合之前或之后与胺组合，所以本发明的吸收剂可以以许多形式使用。聚合物树脂组分可以加工成任何所需形式（成型制品，溶液），然后可以加入二胺或多胺以便原位产生吸收剂。与现有技术的废吸收剂组合物不同，本发明的那些可以通过加热或通过加入凝胶破坏剂将凝胶液化来转化成可泵送液体。通过沉淀或蒸馏从液体中回收有用的吸收剂。

摘要： Graft polymers are prepared by reacting thermoplastic copolymers comprised of alkenyl aromatic monomers and carboxylic acid moieties such as .alpha.,.beta.-unsaturated dicarboxylic acid anhydrides with mono-amine functionalized polyoxyalkylene ethers. The graft polymers are useful for the production of formed products such as injection molded articles and in blends or alloys with other thermoplastic resins such as polystyrene.
