Abstract
Polymeric products contain carbonyl groups other than polyvinyl ketone are treated with alkaline agents to yield soluble bodies having an increased viscosity. Suitable polymeric compounds include interpolymers of acrolein or vinyl methyl ketone and acids such as acrylic acid, vinylacrylic acid, maleic acid, fumaric acid or their derivatives such as their anhydrides, esters or nitriles. In examples (1) an interpolymer of vinyl methyl ketone and methyl acrylate prepared in the presence of acetaldehyde, octylphenol, hydrogen peroxide and benzoyl peroxide, is dissolved in acetone and methanol and treated with sodium methylate; (2) an interpolymer of acrolein, styrene and methyl acrylate prepared in the presence of propionaldehyde and benzoyl peroxide, or an interpolymer of vinyl methyl acetone and vinyl acetate prepared in the presence of acetaldehyde and benzoyl peroxide, is dissolved in acetone and treated with pyridine, (4) an interpolymer of vinyl methyl ketone and acrylic or fumaric acid is treated with caustic soda. Specification 482,440 is referred to.
