摘要： A process is provided for the preparation of expanding-contracting hydrogel composites which process comprises the steps of adding solid particles of a polyelectrolyte to a polyvinyl alcohol solution and subjecting the mixture to a low temperature treatment to cause gelation of the polyvinyl alcohol with the polyelectrolyte dispersed as a heterogeneous phase (i.e. solid particles) within the polyvinyl alcohol gel. Hydrogel composites made by the process exhibit high strength and a capacity to expand and contract over a wide range with changes in environment.

摘要： A method of manufacturing block copolymers containing a polyorganosiloxane segment, by dual polymerization involving (i) polycondensation of a silicone block followed by (ii) the free radical polymerization of a monomer that can be polymerized by free radical polymerization, such as a vinyl containing organic monomer. Initiation of free radical polymerization in step (ii) is carried out with a carbonyl functional group attached to the silicone polymer block. The carbonyl functional silicone polymer, preferably an aldehyde functional silicone polymer, is included as one component of a copper-based Redox initiating system. The method ensures no free homopolymerization, complete reactivity, and various polymer architectures are possible, including for example, polymeric structures such as AB, ABA, (AB).sub.n, brush, and radiant types. The method is fast, effective, convenient, and easier to control than typical ionic polymerization techniques. The silicone-organic block copolymers obtained by the process have utility as polymeric surfactants or as solubility modifiers.

摘要： A method in which radical polymerization of a vinyl monomer is initiated by an ozonide group attached to a silane or a siloxane polymer. The method is particularly useful for preparing organic polymers having a silicone chain end, or for preparing wide ranges of silicone/organic polymers and copolymers with varied architecture, i.e., ABA block copolymers, comb polymers, star polymers, and hyper-branched polymers. In one embodiment, the method is carried out by simply heating a vinyl monomer in the presence of a silane containing ozonide functionality. The ozonide silane is obtained by exposing silanes or siloxanes having an alkyl group containing a double bond to ozone. Surprisingly, an ozonide attached to an organosilicon compound was found to be stable, and capable of initiating vinyl polymerization upon heating to moderate temperatures, i.e., about 70.degree. C.

摘要： This invention relates to hollow elongate articles such as tubing and fibers formed from non-crosslinked polyvinyl alcohol. The articles are prepared by extruding a solution of polyvinyl alcohol in the shape of the desired article into a coagulating bath concurrently with a stream of a non-solvent for the polymer. The stream occupies the area corresponding to the interior cavity of the article and prevents collapse of the cavity until the article has solidified in the coagulation bath.
