Abstract: A process for the continuous polymerisation of vinyl monomers with formation of vinyl polymers having a molecular weight of Mn = 1000 to 20,000, characterised in that the polymerisation is carried out in an annular gap reactor with a gap of from 0.5 to 10 mm in width, in that the annular gap is delimited on the inside by a rotor, and in that the polymerisation is carried out at a temperature of from 110 to 270 DEG C.

Abstract: The invention relates to novel 2,2-dialkylpentane 1,5-diisocyanates, 2,2-dialkylpentane-1,5-diurethanes and 2,2-dialkylpentane-1,5-dicarbamoyl chlorides of the formula in which R , R denote identical or different linear C1- to C12-alkyl radicals, branched C3- to C12-alkyl radicals, branched C2- to C12-alkenyl radicals, branched C4- to C12-alkenyl radicals or the radicals R and R together denote an alkylene group having 4 to 7 C atoms which is unsubstituted or substituted by one to 5 C1- to C4-alkyl groups and X denotes an NCO-, NH-CO2R -, NHCO2R - or NHCOCl- group, in which R and R are identical or different and denote a linear C1- to C20-alkyl radical, a branched C3- to C20-alkyl radical or a C5- to C12-cycloalkyl radical. The 2,2-dialkylpentane-1,5-diurethanes are, for example, pest control agents and are suitable, as are the 2,2-dialkylpentane-1,5-dicarbamoyl chlorides, for example, for the preparation of 2,2-dialkylpentane 1,5-diisocyanates, which in turn are used for the preparation of compact or cellular plastics by the polyisocyanate polyaddition process.

Abstract: Aqueous dispersions of polyurethanes which are crosslinkable by the action of high energy radiation contain (a) a polyisocyanate, (b) a polyol having a molecular weight of from 400 to 6,000 g/mol, (c) if required, a polyol having a molecular weight of from 62 to 399 g/mol, (d) if required, a polyamine having two or more amino groups which are reactive to isocyanate, (e) if required, an aminoalcohol having one or more amino groups which are reactive to isocyanate, (f) a compound containing ionic groups or groups which can be converted into ionic groups and one or more hydroxyl or amino groups which are reactive to isocyanate (g) if required, a monofunctional polyetheral and (h) a compound having one or more ethylenically unsaturated groups and one or more hydroxyl groups. The compound having an ethylenically unsaturated group (h) is used in amounts corresponding to 0.02-0.08 gram equivalent, based on the polyisocyanate (a), of OH, and the polyurethane, dissolved in dimethylformamide, has a Fikentscher K value greater than 40 or is insoluble in dimethylformamide.
