The resultant product falling from the polymerization contains substantially only soluble hydrophilic polymers and copolymers.Type: GrantFiled: January 2, 1975Date of Patent: October 26, 1976Assignee: Ceskoslovenska akademie vedInventors: Miroslav Stol, Vladimir Stoy, Zdenek Tuzar

Patent number: 3962195Abstract: A furan, a maleic anhydride and at least one unsaturated compound selected from a conjugated diene, e.g., butadiene and a vinyl aromatic, e.g., styrene are reacted in presence of a free-radical initiator, e.g., an organic peroxide or azo compound for example di-t-butyl peroxide or 2,2'-azobis(2-methylpropionitrile), in solution, e.g. in a hydrocarbon solution for example in toluene to produce a terpolymer. In one specific embodiment, furan, maleic anhydride and styrene and in another butadiene in lieu of the styrene are selected monomers. White powdery polymers are produced which can be converted to metal carboxylate salts. Additionally, the unsaturation in the polymer backbone permits crosslinking that is of value in the formation of protective coatings. Pendant anhydride groups are also crosslinking sites as by reaction with a diol.Type: GrantFiled: June 11, 1973Date of Patent: June 8, 1976Assignee: Phillips Petroleum CompanyInventors: George A. Moczygemba, Henry L. Hsieh

Patent number: T959006Abstract: this invention concerns novel curing systems useful for curing unsaturated polyester/monomer mixtures such as the polyester of propylene glycol, phthalic anhydride and maleic anhydride, with styrene as the monomer. The curing system is the complex formed by the reaction of (1) a cobalt compound, such as Co(OH).sub.2 or CoCO.sub.3 (2) and acid of the formula ##STR1## wherein R is a straight or branched alkyl of 1-20 carbons which may be monosubstituted with hydroxyl, aryl of 6-10 ring carbons and cycloaliphatic of 6-10 ring carbons, and (3) a nitrogen component of the formula ##STR2## wherein R and R' are independently selected from straight and branched alkyl of 1-10 carbon atoms which may be monosubstituted with hydroxyl. The acid residue in the complex comprises from about 0.2 to about 20.0% by weight of said complex, the cobalt compound, as percent cobalt metal, from about 0.1 to about 10.0% by weight, and the nitrogen compound residue from about 65 to about 90% by weight.Type: GrantFiled: June 30, 1976Date of Patent: June 7, 1977Inventors: James L. Suggs, William W. Blount, Jr.
