WATER-SOLUBLE ADHESIVE COMPOUNDS AND THEIR USE IN PREPARING PERMANENTLY TEMPERATURE-RESISTANT SPLITTABLE FILMS ADHERING TO DAMP SUBSTRATES

摘要

The invention relates to a water-soluble adhesive compound which consists of:… a) 100 parts by weight of at least one water-soluble copolymer composed of… 55 to 90% by weight of at least one vinylcarboxylic acid,… 5 to 35% by weight of at least one hydroxyl group-containing (meth)acrylate,… 1 to 15% by weight of at least one N-substituted (meth)acrylamide derivative and… 0.05 to 10% by weight of at least one vinylcarboxylic acid salt,… b)50 to 200 parts by weight of at least one water-soluble plasticiser from the group comprising the polyoxyalkylenes having a molecular weight of up to 1000 and… c) 0.1 to 8 parts by weight of a cross-linking agent, and the use of these adhesive compounds for preparing jointing tapes.
