Abstract: Use is claimed of alpha , beta -ethylenically unsaturated carboxylic acids in reducing the residual monomer content in aqueous radical emulsion polymerisation of mixtures comprising (A) 4-8C diene(s); (B) nitrile(s) of alpha , beta -ethylenically unsaturated carboxylic acids; (C) amide(s) and/or N-methylolamide(s) of alpha , beta -ethylenically unsaturated 3-6C mono- or 4-6C di-carboxylic acids; and optionally also (D) comonomers comprising vinyl aromatics, esters of alpha , beta -ethylenically 3-6C mono- or 4-6C di-carboxylic acids with 1-12C alkanols and/or esters of vinyl alcohol with 1-20C monocarboxylic acids. The unsaturated acid is added in an amount of 0.05-2.5 (especially 0.2-1)wt.% based on monomers (A) - (D) before or during the polymerisation or before an optional post-polymerisation. Aqueous polymer dispersions thus obtained are claimed, as is also their use in impregnating textiles, leather or (especially) fleeces.

Abstract: An aqueous polymer dispersion (I) having a low residual monomer content is prepared by radical aqueous emulsion polymerisation of an ethylenically unsaturated monomer whereby (a) the monomer(s) and an initiator system (II) are mixed and (b) optionally allowed to react for up to one hour and (c) addition of a different initiator system (III) with full conversion of the monomer(s).

Abstract: Aq. dispersions (I) contain (A) a radically polymerised polymer contg. 5-50 wt.% ethylenically unsatd. acid monomer units (A1) and (B) an anionically polymerised polymer. Also claimed is a process for the prodn. of (I), by producing polymer (A) or (B) in organic solvent in the presence of (B) or (A), or producing (A) and (B) in soln. separately and mixing the solns. or dispersions obtd., then dispersing the mixt. in water and removing organic solvent as required. Also claimed are substrates coated with (I).

IPC: C08F6/00
Abstract: Post-polymerisation reduction of the residual monomer content of a liquid solution, mixture, melt, suspension or dispersion obtained by free radical polymerisation is effected by adding a redox initiator system at a suitable temperature, the liquid in the reactor being mixed for the least possible time and at least one of the components of the initiator being added gradually to the liquid for a dose time which is 10-250 times the mixing time of the liquid.

Abstract: Adhesives (I) are claimed, contg. a copolymer (II) with an average Mn of 2000-250,000 and opt. less than 40 wt.% homopolymer blocks with a mol. wt. greater than 1/20 of Mn, obtd. by anionic polymerisation of (a) 10-90 wt.% vinylaromatic cpd., (b) 10-90 wt.% conjugated diene and (c) 0-30 wt.% other comonomers.
