The chips have a granular shape and have a size in the range from about 0.25 mm to about 20 mm in diameter.Type: GrantFiled: July 12, 2000Date of Patent: October 14, 2003Assignee: Gloucester Co., Inc.Inventors: Theodore P. Anderson, Lawrence H. Boise, Robert G. Modrak

Patent number: 6632868Abstract: A nanocomposite concentrate composition comprising about 10 weight percent to about 90 weight percent of a layered silicate material and about 10 weight percent to about 90 weight percent of a matrix polymer comprising about 90-99.8% by weight of a polyolefin and about 0.2% to about 10%, preferably about 0.2% to about 3%, more preferably about 1% to 3% by weight, of a maleic anhydride-modified polyolefin, based on the total weight of polyolefins, wherein the layered silicate material is dispersed uniformly throughout the matrix polymer. Shearing of the concentrate and later (after shear) addition of an added matrix polymer avoids thermal degradation of the added matrix polymer and optimizes the dispersion of the nanomer throughout the matrix polymer; provides increased tensile strength; and reduces degradation of the polymer by melt formation of a concentrate thereby decreasing heat degradation of added matrix polymer.Type: GrantFiled: April 25, 2001Date of Patent: October 14, 2003Assignee: Amcol International CorporationInventors: Guoqiang Qian, Jae Whan Cho, Tie Lan

Patent number: 6632870Abstract: Flame-retarded transparent plastic compositions comprising polyhalgenated trimethylphenyl indan. The polyhalogenated trimethylphenyl indan is a mixture of polyhalogenated trimethylphenyl indanes having each 3 to 9 halogen atoms. The halogen may be bromine or a mixture of bromine and chlorine. The transparent plastic is selected from polycarbonate, polymethylmethacrylate, and polystyrene. The polyhalogenated trimethylphenyl indan is present in an amount of up to about 40% by weight. The transparent plastic flame-retarded material is prepared by mixing the plastic matrix with a flame-retardant effective amount of a polyhalogenated trimethylphenyl indan.Type: GrantFiled: November 29, 2000Date of Patent: October 14, 2003Assignee: Bromine Compounds Ltd.Inventors: Ita Finberg, Lev Utevski
