Title: Method of adhesively uniting or coating chlorine-containing thermoplastic material
IPC: B32B27/00
Filed: 1961-04-24
Abstract: A halogen-containing compound containing two or more epoxy groups is used, in conjunction with an epoxy resin hardening agent, for coating or for effecting adhesive union between chlorinecontaining thermoplastic materials, e.g. polyvinyl chloride, polyvinylidene chloride, chlorinated or sulphochlorinated polyethylene. Suitable halogen-containing epoxy compounds are condensates of epichlorohydrin with halogen - containing polyhydrin alcohols or phenols; copolymers of vinyl chloride, vinylidene chloride, chloroprene or chlorinated styrene with unsaturated monomers containing epoxy groups, e.g. allyl glycidyl ether or glycidyl esters of unsaturated acids such as acrylic, methacrylic or chloroacrylic; a mixture of copolymer of vinyl chloride and allyl glycidyl ether with an epichlorohydrin polymer as described in Specification 941,871 or with a telomerization product of allyl glycidyl ether and carbon tetrachloride of formula <FORM:0988770/C3/1> in which n is greater than 2.  The adhesives may be diluted with methylene chloride, 1,2 - dichloroethane, or 1,2- or 1,3 - dichloropropane. In Examples (1) a copolymer of vinyl chloride and allyl glycidyl ether was mixed with 1,2-dichloroethane and 2,2-di-(4-aminocyclohexyl)propan and the mixture used for coating or cementing objects of polyvinyl chloride; (2) is similar, but the curing agent used was triethylene tetramine; (3) the adhesive consisted of a copolymer of vinyl chloride and allyl glycidyl ether, a polymer of epichlorhydrin, and 2,2-di-(4-aminocyclohexyl)-propane; (4) is similar to (3) but a telomerization product of carbon tetrachloride and allyl glycidyl ether replaces the epichlorohydrin polymer; (5) polyvinyl chloride specimens were stuck together with the diglycidyl ether of 2,2 - bis - (4 - hydroxy - 3,5 - dichlorophenyl)propane, 1,2-dichloroethane and 2,2-di-(4-aminocyclohexyl)propane.ALSO:A halogen-containing compound containing two or more epoxy groups is used, in conjunction with an epoxy resin hardening agent, for coating or for effecting adhesive union between chlorine-containing thermoplastic materials, e.g. polyvinyl chloride, polyvinylidene chloride, chlorinated or sulphochlorinated polyethylene.
