Abstract

The size of rubber particles in a synthetic rubber latex is increased by the addn. of 0.01-10wt. %, calculated as solids, of a copolymer latex, with pH is not 4, prepd. by polymsg., in the presence of is not 1 anionic surfactant, a mixt. contg. 3-30wt. % of acrylic, methacrylic, itaconic and/or crotonic acid and 97-70wt. % of a 1-12C alkyl acrylate. The 2 latices are mixed at pH is not 6, to agglomerate the rubber particles. The particles are enlarged from 0.05-0.18 mu to 0.3-1 mu, but macro-agglomerates are not formed and special dispersion stabilisers or emulsifiers are not needed. The heat stability and the mechanical props. of the rubber are not altered and agglomeration is rapid.
