Abstract: A process for the preparation of heat-sensitive latices, characterised in that a mixture of 45-80 % by weight of butadiene, 10-45 % by weight of acrylonitrile, 0-20 % by weight of styrene, 0.5-10 % by weight of (meth)acrylic acid, 2-10 % by weight of (meth)acrylamide and 0-5 % by weight of (meth) acrylamido-N-methylolmethyl ether is polymerised on radical initiators in an aqueous emulsion in the presence of 1-10 % by weight of an emulsifier or a mixture of several emulsifiers, only a small proportion of the total quantity of emulsifier being present at the beginning of polymerisation, the remainder being added in the course of polymerisation.
