ABSTRACT:
Resins suitable for adhesives are based on .alpha.-methyl styrene, styrene and phenol in certain percentages, viz. 25 to 63, 35 to 73 and 2 to 15 percent by weight, respectively.
Combinations of resin, ethylene vinyl acetate copolymer, atactic polypropylene, ethyl acrylate copolymer or a thermoelastomer and optionally a wax or tackifying oil yield excellent adhesives, in particular hot-melt adhesives.
