Abstract: The present invention relates to a method for performing a polymerization process in a stirred reactor, wherein a critical time window is determined by means of a monitor of at least one polymerization process parameter and an associated process window, and when a critical time window is present, an adaptation of process conditions is made in order to configure the polymerization process to conform to the process window.

Abstract: Aqueous polymer dispersions based on copolymers formed from vinyl-aromatics and conjugated aliphatic dienes having a mean particle size of from 80 to 150 nm are obtainable by free-radically initiated emulsion copolymerization of (a) from 19.9 to 80 parts by weight of at least one vinylaromatic compound, (b) from 19.9 to 80 parts by weight of at least one conjugated aliphatic diene, (c) from 0.1 to 10 parts by weight of at least one ethylenically unsaturated acid and (d) from 0 to 20 parts by weight of at least one other monoethylenically unsaturated monomer, where the sum of the parts by weight of monomers (a), (b), (c) and (d) is always 100, in an aqueous medium in the presence of at least one degraded starch with an intrinsic viscosity ? of less than 0.07 dl/g, using at least 0.9% by weight, based on all of the monomers used, of initiators selected from peroxodisulphates, peroxosulphates, azo initiators, organic peroxides, organic hydroperoxides and hydrogen peroxide, wherein at least 30% by weight of the initiators are initially charged in the aqueous medium together with the degraded starch and the monomers and the remaining initiators are metered into this initial charge under polymerization conditions. Processes for preparing this dispersion by emulsion polymerization of the monomers (a), (b), (c) and optionally (d) in the presence of a degraded starch with an intrinsic viscosity ? of less than 0.07 dl/g, where a portion of the initiator is initially charged together with the aqueous solution of the degraded starch in the reactor, and the remaining initiator and the monomers are metered in under polymerization conditions, and the use of the aqueous polymer dispersions as binders, adhesives, sizes for fibres or for producing coatings.
