摘要:
A process for polymerizing vinyl chloride alone or a mixture of vinyl chloride and other vinyl monomer(s) with hydroxy containing monomer(s), and the copolymer obtained thereby. The hydroxy containing monomer(s) is obtained by the partial allylation of dihydroxy or polyhydroxy alcohols. The copolymers are prepared by suspension polymerization. The presence of the hydroxyl groups significantly modifies the characteristics of the polymers. Plasticizer-take-up is increased and dry-time is reduced significantly. Furthermore, the hydroxyl groups become the sites for postpolymerization reactions due to their polarity and reactivity.
摘要:
An improved method is provided for copolymerizing vinyl chloride with allyl glycidyl ether and a vinyl ester. The copolymers so formed include 70-99 weight percent of vinyl chloride, 0.05-15 weight percent of allyl glycidyl ether, and 0.05-15 weight percent of a vinyl ester, preferably vinyl acetate. The copolymers of this invention can be compounded to provide films exhibiting improved heat stability, low haze, and good adhesion to solid surfaces such as glass and metal. The compounded resins thus obtained may be especially advantageously used in forming the interlayer of laminated safety glazings, such as vehicle windshields and architectural glazings.The copolymerization of vinyl chloride, allyl glycidyl ether, a vinyl ester and small amounts of an unsaturated organic trifunctional silane provide self-adhesion without gelation.

A laminated safety glass is formed of an inboard glass sheet, an outboard glass sheet and a plasticized polyvinyl chloride containing interlayer therebetween. The outboard glass sheet has an average transmittance of radiation in the range of 300-340 nm of less than about 20%, and preferably less than about 1%. The outboard glass sheet also has an average transmittance of radiation in the range of 340 to 500 nm of more than about 50%. The outboard glass sheet may be formed of an ultraviolet radiation absorbing glass, such as an ultraviolet radiation absorbing green glass.
摘要:
Laminated safety glass includes a pair of glass sheets bonded together with a self-adhering composite interlayer. The composite interlayer is formed of a support layer including a plasticized PVC containing film and a polymeric adhesive layer on one, or preferably both, of the major surfaces of the support layer. The adhesive layers are formed of a polymeric material which is capable of adhering to the PVC containing support layer and to the glass sheets. The respective refractive indices of the adhesive layers and the support layer are matched as closely as possible in order to eliminate optical distortion caused by interfacial reflections of incident light. A preferred copolymer resin for forming the adhesive layers is poly(vinyl chloride-co-vinyl acetate-co-maleic acid).
