Abstract

Mercapto group-containing polyethers are prepared by reacting a halogen substituted polyether with a substituted or unsubstituted dithio-carbamate and hydrolysing the product. Specified polyethers are polymers and copolymers of epihalohydrins, and products obtained by replacing the hydroxyl groups of hydroxyl-terminated polyethers either by halgen atoms, e.g. by using hydrogen halides, thionyl halides, or phosphorus halides, or by chloromethyl groups using hydrogen chloride and a formaldehyde derivative; specified hydroxy - terminated polyethers are those obtained by polymerizing or copolymerizing epoxides, optionally in the presence of a polyfunctional initiator, e.g. ammonia, hydrazine, polyols, amino-alcohols, polyamines, diepoxides, glycidol or 3-hydroxymethyloxetane. The examples describe the reaction of sodium N,Ndimethyl-dithiocarbamate with (1) poly-(epichlorohydrin), and (3) a propylene oxide/epichlorohydrin/ethylene glycol copolymer.ALSO:Mercapto group-containing polyethers are prepared by reacting a halogen-substituted polyether with a substituted or unsubstituted dithiocarbamate and hydrolysing the product. Specified polyethers are polymers of epihalohyrins, copolymers thereof with alkylene oxides, and products obtained by replacing the hydroxyl groups of hydroxyl terminated polyethers either by halogen atoms, e.g. by using hydrogen halides, thionyl halides, or phosphorus halides, or by chloromethyl groups using hydrogen chloride and a formaldehyde derivative; specified hydroxy-terminated polyethers are those obtained by polymerizing or copolymerizing epoxides, optionally in the presence of a polyfunctional initiator, e.g. ammonia, hydrazine, polyols, phenol/formaldehyde reaction products, amino-alcohols, polyamines, diepoxides, glycidol or 3-hydroxymethyloxetane. The products may be cured by air oxidation, or converted to graft polymers by reaction with vinyl monomers, e.g. methyl methacrylate. The graft polymers may be converted to thiourethanes by reaction with polyisocyanates; or hydroxylated and then either cured by reaction with polybasic acids or polyisocyanates, or reacted with hydroxyl groups of polyoxyalkylenes, polyesters, polyamides or polyurethanes. The examples describe the reaction of sodium N,N-dimethyldithiocarbamate with (1) poly-(epichlorohydrin) and (3) a propylene oxide/epichlorohydrin/ethylene glycol copolymer; in (2) and (4) the products of (1) and (3) respectively are grafted with methyl methacrylate in solution in benzene in the presence of azodiisobutyronitrile; in (5) the product of (4) is reacted with (a) tolylene diisocyanate, (b) the reaction product of glycerol, diethylene-glycol and tolyene diisocyanate, and (c) an isocyanurate polymer of tolylene diisocyanate, and the product cured.
