Abstract: A mixture (A) of vinylidene chloride and other monomers giving a co-polymer of softening point -20 degrees C to 40 degrees C, is first polymerised to a conversion of at least 90%. A mixture of vinylidene chloride, with other monomers of desired, giving a co-polymer of softening point 60 degrees to 200 degrees C is then added and immediately polymerised. The ratio of (A) to (B) is from 1:2 to 10:1 and the composition is such that the co-polymer product contains at least 60% vinylidene chloride. The aqueous dispersions obtained can be for coating plastic films, paper, parchment, metallic foils, etc. giving coating with excellent flexibility, elasticity, resistance to ageing and heat-sealing properties. and with reduced tendency to blocking.

Abstract: Copolymers contg. (A) 60 - 94.6% wt. vinylidene chloride, (B) 5 - 39% wt. monomers giving water-insol. homopolymers (e.g. vinyl esters, acrylates), (C) 0.2 - 10% wt. alpha, beta-unsatd. mono- or di-carboxylic acids and (D) 0.2 - 5% of N-methylolamides, N-alkoxymethylamides or N-carbalkoxymethylamides of these acids, are used for coating paper. Use is partic. for parchment paper. Adhesion is good in both wet and dry conditions.
