摘要： Solvent-soluble, heat-hardening, non-gelled resins are provided by etherifying a polymethoxy siloxane with an unsaturated hydroxy-functional compound, with some of the methoxy groups of the siloxane being preserved for subsequent cure. This ether is then copolymerized with other ethylenically unsaturated materials to form a copolymer which includes methoxy groups carried by the siloxane in order to improve the elevated temperature cure of the resin. The preparation of an unsaturated ether by a reaction in which alcohol instead of water is removed coupled with subsequent polymerization enables larger proportions of the resinous siloxane material to be incorporated into the resin.

摘要： Multiple sequence block copolymers of silicone and styrene having the formula: (1) (ABA)x ARE PRODUCED, WHERE A represents repeating diorganosiloxy units and B represents a polystyrene chain. This ABA chain is repeated from three to 10 times. The materials have high elongation and tensile strength and are useful in the formation of strong, elastic films.

摘要： Graft-polymers of,.alpha.,.alpha.'-disubstituted .beta.-propiolactones on isobutylene-triene copolymers are prepared by reacting an isobutylene-triene copolymer with maleic anhydride and possibly with other functionalizing agents adapted to introduce acid and ester groups in the copolymer molecule and by neutralizing or hydrolyzing, or both, with a tetraalkylammonium base, said functional groups, said neutralization or hydrolysis, or both, being followed by a grafting reaction with pivalolactone.

摘要： Water-swellable crosslinked polymer gels show increased adhesion to wood and other cellulosic materials and also increased waterabsorbing capacity when there is incorporated in the gel up to about an equal weight of a cationic polymer such as a polyalkylenepolyamine, a polyalkylenimine, or a cationic polyacrylamide. The increased adhesion of both dry and waterswollen gels makes the invention useful in fire fighting and in the preparation of water-absorbing laminates.
