There is provided a process for producing a styrenic graft copolymer which comprises coplymerizing a styrenic monomer and a styrenic monomer having a hydrocarbon radical with an unsaturated bond in the presence of a catalyst comprising as primary ingredient (A) a transition metal compound and (B) a contact product of an organoaluminum compound and a condensation agent or (C) a compound which produces an ionic complex by reacting with the above-mentioned transition metal compound and subsequently graft polymerizing an ethylenically unsaturated monomer onto the resultant styrenic copolymer.
The above-described styrenic graft copolymer is greatly improved in terms of compatibility, adhesivity, coatability and wettability while preserving heat resistance and chemical resistance thereof, and thus effective as a variety of constructional materials and compatibilizing agents. Furthermore, the composition or multi-layer material comprising the above-mentioned styrenic graft copolymer is widely utilized in a variety of application field including film, sheet, especially stampable sheet, container, packaging material, automobile parts, electrical and electronic parts, etc.

This invention relates to a composition comprising a mixture of a brine and a liquid oil, and (A) a viscosity increasing amount of at least one ester of a carboxy-containing interpolymer or salt thereof wherein the interpolymer is prepared by polymerizing an olefin selected from the group consisting of alpha-olefins and vinyl aromatic monomers with at least one alpha, beta-unsaturated carboxylic acylating agent, and provided that when the olefin is vinyl toluene, then the alpha, beta-unsaturated carboxylic acylating agent is an alpha, beta-unsaturated dicarboxylic acylating agent. The compositions of the present invention are useful as drilling fluids as well as completion fluids. The esters of the carboxy-containing interpolymer or salts thereof provide beneficial viscosity, formation stabilization, emulsification and rheology properties to the fluids.
