摘要：the invention relates to haftklebstoffe, preferably 60 to 85 wt.%pfropfcopolymeres and 15 to 40 wt.% monomerweichmacher as phthalate orphosphatweichmacher included.the pfropfcopolymere consists of 5 to 30 wt.%pfropfgrundlage and 70 to 95 wt.% grafted monomer units. the pfropfgrundlage is acopolymeres 40 to 85%.-% \äthyleneinheiten and 15 to 60 wt.% vinylacetateinheitenand, if necessary, up to 10 wt.% of units further unsaturated compounds.they may befully or partially replaced by other pfropfgrundlagen. the grafted monomer units consistof 30 to 80% by weight.-% vinylestereinheiten kurzkettiger carboxylic acids, particularlyacetate, 20 to 70% by weight.-% vinylestereinheiten l\ängerkettiger carboxylic acids,for example vinyllaurat, and \\/ or estereinheiten alpha,betaunges\ättigten carboxylicacids with l\ängerkettigen alcohols and \\/ or dicarboxylic acids with

l\ängerkettigen alcohols, 0.5 to 15 wt.% n vinyl 2 pyrrolidon and 0 to 20% byweight.-% more olefinisch unsaturated copolymerisierbaren monomer units. this

pfropfcopolymeren wereden produced by free radical grafting of a solution of thecopolymers in the monomergemisch.the erfindungsgem\ä\ßen haftklebstoffecan be used in particular as schmelzhaftklebstoffe.
