Patent number: 5183865Abstract: This invention is directed to a shelf-stable, powder composition adapted to form a high T.sub.g, thermally stable, impact resistant thermoset material. The composition consists essentially of a mixture of an allyl-functional prepolymer component and polymaleimide component. The allyl-functional prepolymer component is the reaction product of an aromatic allyl-functional compound and a modifying compound wherein the compounds contain mutually reactive funtionalities such as an aromatic allyl-functional epoxide compound and a modifying amine compound.Type: GrantFiled: January 16, 1991Date of Patent: February 2, 1993Assignee: Ford Motor CompanyInventor: Mohinder S.

Patent number: 5180787Abstract: The present invention relates to fire retardant polymer compositions possessing a non-liner structural configuration resulting by the reaction of N-tribromo-phenylmaleimide, with or without comonomer, with a preformed backbone polymer, in which the bromine content is above 1.2% by weight bromine. The polymer is selected from polystyrene, polyolefins, polyamides, rubbers, polyesters, acrylics, polymeric dienes and mixtures or copolymers thereof. The comonomer present with the N-tribromophenyl-maleimide is selected from the group consisting of acrylonitrile, styrene and vinyl chloride. According to the invention the non-linear structural configurations are obtained either by grafting or crosslinking of the N-tribromophenylmaleimide onto the preformed backbone polymer in the presence of free radical producing means. Optionally, synergistic fire retardant additives such as antimony oxide are incorporated in the compositions.Type: GrantFiled: November 26, 1990Date of Patent: January 19, 1993Assignee: Bromine Compounds, Ltd.Inventors: Leonard M. Shorr, Theodor M. Fishler, Shaul Yanay, Michael Rumack

Patent number: 5177151Abstract: This invention relates to a comb-shaped graft copolymer, to a process for making the comb, and to a polymer blend made with the comb. The comb is made by a free radical polymerization of an ethylenically unsaturated monomer with a macromolecular monomer ("macromer" for brevity) of a haloalkylene oxide ("HAO" for brevity) homopolymer, random or block copolymer. The comb copolymer and blends of the comb with a polymer(s) may be cured. A comb with a terminal acrylyl or methacrylyl group or "head" and pendant polyether chains, which always include some HAO repeating units, may be made in an emulsion or suspension polymerization process which provides a comb having adequately high molecular weight so that the comb may be used in blends. The preferred comb of epichlorohydrin has a (meth)acrylyl head at one end, through which it (the macromer) is polymerizable, and a terminal hydroxyl (OH) group, or an end-capping group derived from the OH group at the other end.Type: GrantFiled: June 8, 1992Date of Patent: January 5, 1993Assignee: The B. F. Goodrich CompanyInventor: Simon H. Yu
