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.

Abstract: A process for the spinning of filaments of a substantially uniform thickness. Spinning fluid is forced under pressure from a storage means through conduit means into a spinneret and out spinning nozzles. The pressure of the spinning fluid is controlled according to the value measured by flow measuring means situated in the conduit. Significant pressure variation in the system is measured by measuring the pressure on the spinning fluid feed. The pressure variation measured is translated into switching means preset to operate in relation to the number of spinning nozzles operating. The appropriate preset flow rate controller is utilized depending upon the value measured by the pressure measuring means.
