FIELD: adhesive compositions for polyvinyl chloride-based adhesive tapes. ^ SUBSTANCE: claimed adhesive contains perchlorvinyl resin, plasticizer, pine-wood rosin, and filler. Mixture of dioctylphthalate and chlorinated alpha-olefins, obtained from waste of ethylene oligomerization, is used as plasticizer, and activated mixture of natural zeolite and calcium oxide is used as filler. Adhesive tapes of present invention are useful as sealing and protective coatings for gas and oil line coil. ^ EFFECT: polyvinyl chloride-based adhesive tapes with improved adhesive quality and reduced plasticizer migration from tape into adhesive tape. ^ 3 ex, 1 tbl |
