Abstract
Neoprene compositions containing a latex of a copolymer of chloroprene with an .alpha.,.beta.-ethylenically unsaturated carboxylic acid, such as methacrylic or acrylic acid, the polymerization being conducted in the presence of polyvinyl alcohol, and zinc oxide or zinc hydroxide which has been previously contacted with an alkali metal hydroxide are particularly well suited for use in contact adhesives.
