The elastomer is based on homopolymers orncopolymers of alkyl acrylates with vinylnmonomers (vinyl chloride, styrene, methyl methacrylate,nvinyl acetate, 1,3-butadiene) andnit is produced by emulsion or suspension polymerizationnat 0 to 100 ° C. monomersnare added to the reaction mediumnto one, but not more than four times, withnthe reaction is conducted in the presence of 0.4 toninitiator or initiator system;nquantities up to 5 hnmonomer conversion of at least 70%nhowever, production leads to conversionn85 to 100 ° / o. The reaction is carried outnat least two different temperature levelsn20 to 50 ° C, 70 to 95 ° C or beyondnthe addition of radical scavengers and decomposers' of peroxides.nThe dispersion obtained is optionalnafter isolation, the elastomer itself is a substratenor a toughness componentnmacromolecular substances. |
