Polychloroprene for use in adhesive compositions and having the advantage of remaining in a single phase is prepared by effecting polychloroprene polymerization in the presence of a binary emulsifying system of 1.8 to 3% of resinic derivative and 0.1 to 1% of a fatty acid or salt thereof. Alternatively, a ternary emulsifying system may be used comprising 1 to 3% of the resinic derivative, 0.1 to 1.5% of the fatty acid or salt therof and 0.1 to 2.5% of a sticking agent of a colophony derivative or a polydiene resin.

An adhesive composition comprises:- (1) 100 parts by weight of one or more rubbery diene addition polymers having an average molecular weight of at least 30,000 and containing a total of 0À00025-0À12 carboxyl equivalents/100 grams; (2) From 0À1-80 parts by weight of a metal of Group IA, IIA, IIB or IVA of the Periodic Table in the form of an organic solvent-soluble metalorganic resin; and (3) 50-450 parts by weight of an organic solvent-soluble resin compatible with (1). Ingredient (1) is preferably a carboxylated polybutadiene or butadiene-styrene copolymer. The rubber may also be a mixture of carboxylated and non-carboxylated polymers. The resin (2) may be an oil-soluble heat-hardenable phenol-formaldehyde resin or a rosin acid and the metal may be lithium, sodium, magnesium, calcium, barium, zinc or lead. Resin (3) is suitably a poly-#-pinene or an ethylene glycol ester of polymerized rosin. The compositions may contain filler and a small amount of solvent for use as mastics or dissolved in solvents for brushing and spraying. Ingredients (1) and (2) may be reacted together by masticating at high temperatures. Additionally part or all of resin (3) can be constituted by " excess " resin (2) |

Polychloroprene contact adhesive is made by mixing polychloroprene, tackifier, metallic oxide, antioxidants and organic solvent. The contact adhesive is sheared for reducing its ASTM D 1084 Saybolt viscosity by 10 percent or more. Shearing improves the sprayability of the polychloroprene contact adhesive. It makes it more uniform and reduces its viscosity. |
