Patent number: 4340534Abstract: The invention relates to epoxy compounds which can be polymerized to give polyethers and which are formed from polyalkyl-1-oxadiazaspirodecanes of the formula ##STR1## in which X is a group ##STR2## and an epihalogenohydrin by linking the nitrogen atom of the 5-membered ring to the 2,3-epoxypropyl radical. Polyethers which have degrees of polymerization of up to approx. 50 and which exhibit a very low volatility and are suitable as light stabilizers for organic polymers can be obtained by heating the epoxides.Type: GrantFiled: October 6, 1980Date of Patent: July 20, 1982Assignee: Hoechst AktiengesellschaftInventors: Hartmut Wiezer, Gerhard Pfahler

Patent number: 4304880Abstract: Improved three component insulating coatings for both wet solvent and dry electrostatic application to transformer wires contain an increased eopoxy resin concentration and a decreased amount of polyvinyl acetal and phenol aldehyde resins. The increased epoxy content gives substantially improved coatings with no adverse dissipation and hydrolytic effects. The epoxy constituent can range from 30-60 per cent by weight providing the ratio of the polyvinyl acetal to phenol aldehyde is kept within the range from 1 to 1 to 2 to 1.Type: GrantFiled: April 28, 1980Date of Patent: December 8, 1981Assignee: General Electric CompanyInventor: Ralph G. Flowers

Patent number: 4291134Abstract: Molding materials containing styrene-acrylonitrile copolymers, in which an additional essential ingredient is from 0.1 to 2.0% by weight, based on the copolymer, of a three-block polymer X-Y-X, where X is a terminal ethylene oxide block and Y is a central propylene oxide block. The proportion of terminal ethylene oxide blocks X, based on block copolymer, is from 5 to 20% by weight, while the central propylene oxide block Y has a number-average mean molecular weight of from 700 to 3,000 and its proportion is from 80 to 95% by weight, based on block copolymer. The number-average molecular weight of the sum of the two terminal blocks X is from 140 to 1,000.Type: GrantFiled: April 9, 1980Date of Patent: September 22, 1981Assignee: BASF AktiengesellschaftInventors: Jurgen Hambrecht, Gerhard Lindenschmidt, Walter Regel
