Abstract: Gels for thermotropic sheets are claimed which are obtd. by light-radiation of a mixt. comprising (A) a non-crosslinked polymer (pref. 5-40 wt.%); (B) a radically-polymerisable monomer (pref. 1-30 wt.%); and (C) water and/or an org. solvent (pref. 30-94 wt.%). Pref. a photoinitiator is opt. also present. Polymer (A) has transparency changes in a 10 wt.% aq. and/or org. solvent soln. and is poly-N-vinylcaprolactam, a copolymer contg. at least 20 wt.% N-vinylcaprolactam, or a polyvinylether. Monomer (B) forms a 3-D network on light-irradiation and ether does not have thermotropic properties of the type specified above or has such properties at at least 20 degrees C above the switching region for polymer (A). (C) is water.

Abstract: Microcapsules containing a bleaching assistant obtained by polymerisation of a monomer mixture comprising (total monomer mixture = 100 wt. %) (a) 5-100 wt. % of at least one ethylenically unsaturated carboxylic acid anhydride, (b) 0-95 wt. % of at least one monoethylenically unsaturated monomer different to monomer group (a), (c) 0-80 wt. % crosslinking monomers having at least two non-conjugated monoethylenically unsaturated groups in the molecule and (d) 0-20 wt. % water soluble monoethylenically unsaturated monomers, in the oil phase of a stable oil-in-water emulsion in the presence of radical forming polymerisation initiators, and optionally continuously or periodically increasing the temperature of the polymerisation reaction mixture during the polymerisation are new. The oil phase of the emulsion contains or consists of the bleaching assistant. Also claimed are washing and cleaning agents containing the encapsulated bleaching agent assistants for the cleaning of textile s.
