Abstract

1527312 Preparation of polymer latices SINTEF 17 Feb 1977 [19 Feb 1976] 06763/77 Heading C3P A polymer latex is prepared by homogenizing an aqueous mixture containing an emulsifier and a water-insoluble solvent for the monomers to be polymerized, which solvent has a watersolubility at 25‹ C. of less than 10<SP>-3</SP> gm./l., whereafter a monomer or mixture of monomers, a water-soluble initiator and optionally further water are added to the homogenized mixture, and the total mixture polymerized. The waterinsoluble solvent may be an optionally halogenated alkane of at least 10 carbon atoms, and is preferably a substance which is a functional component of the final latex, such as a plasticizer or a stabilizer. When the monomer is vinyl chloride. Alternatively the water-insoluble solvent may be a monomer which is copolymerizable with the main monomer, provided that it satisfies the solubility restriction, suitable compounds being C 15 or more alkyl vinyl ethers, esters of formula CH 2 =CHOOCR wherein R is at least C 15 alkyl, and (meth) acrylates of at least C 15 alkanols.
