Abstract: A particle composition (I) contains particles of cross-linked polyvinylprrolidone having a particle size distribution in which as greater than 10 wt.% of particles have a particle size of less than 63 mu m, 0.1-30 wt.% of particles have a particle size greater than 1000 mu m and at least 10 wt.% of particles have a particle size of less than 200 mu m. Independent claims are included for: (i) a compact particulate wash and cleaning agent (II) containing 0.5-20 wt.% of the particle composition (I); (ii) a process for the production of the cleaning agent (II) by mixing 0.5-20 wt.% of the particle composition (I) with the other powdered ingredients; (iii) a process for the production of the particle composition (I) by means of popcorn polymerization by polymerization of a reaction mixture comprising N-vinylpyrrolidone and cross-linking agent in the absence of oxygen and polymerization initiators at upto 200 deg C in substance or using water as a precipitation agent and the particle size the popcorn polymer is controlled by introduction of an inert gas stream into the reaction mixture.

Abstract: Polyurethane adhesive mixtures or polyurethane adhesive solutions contain (a) a polyurethane elastomer which advantageously has a mean molecular weight of not less than 30,000 and which is prepared by reacting (i) one or more essentially linear polyesterpolyols and (ii) one or more chain extenders with (iii) a mixture of 4,4'- and 2,4'-diphenylmethane diisocyanate isomers in a weight ratio of from 60:40 to 40:60 and (b) if appropriate, additives and/or organic solvents.
