Patent number: 4261872Abstract: The invention is concerned with novel autoxidizable compositions comprising an unsaturated acid ester of a glycol monodicyclopentenyl ether, a condensation or vinyl addition polymer, a siccative and a volatile stabilizer, which compositions are uniquely adapted to be formulated with high solids and practical viscosity ranges for coating and/or impregnating purposes.Type: GrantFiled: May 22, 1978Date of Patent: April 14, 1981Assignee: Rohm and Haas CompanyInventors: William D. Emmons, Kayson Nyi

Patent number: 4245068Abstract: The shrinkage of a thermosettable composition comprising an unsaturated polyester and a vinyl monomer capable of cross-linking the polyester is reduced during cure by the addition to the composition of an alkylene oxide polymer which is soluble in the thermosettable composition but which is substantially less soluble in the cured thermoset composition.Type: GrantFiled: December 27, 1977Date of Patent: January 13, 1981Assignee: The Dow Chemical CompanyInventors: James L. Brewbaker, Rodrique L. Marzett, William A. Sprenger

Patent number: 4224427Abstract: The disclosure describes an improved process for the preparation of uniform, spherical beads of up to 5 mm diameter of a crosslinked, water-insoluble hydrogel by suspension polymerization in a concentrated aqueous salt solution of 95-30% by weight of a monoolefinic water-soluble monomer containing at least 5% of a hydroxy substituted hydrophilic vinyl monomer with 5-70% by weight of a terminal diolefinic macromer crosslinking agent in the presence of water-insoluble, gelatinous, strong water-bonding inorganic metal hydroxides as suspending agents in the absence of excess alkali. The hydrogels have a host of pharmaceutical and industrial uses.Type: GrantFiled: June 1, 1978Date of Patent: September 23, 1980Assignee: Ciba-Geigy CorporationInventors: Karl F. Mueller, Sonia J. Heiber, Walter L. Plankl
