ABSTRACT:
Hot melt adhesives containing petroleum resin tackifiers which are prepared by a process wherein (1) a C.sub.8 -- and/or C.sub.9 aromatic unsaturated hydrocarbon-containing feed (optionally containing up to 18 wt. % of C.sub.4 or C.sub.5 unsaturated aliphatic hydrocarbons) is first polymerized completely and thereafter a C.sub.5 -aliphatic unsaturated hydrocarbon-containing feed is added, polymerization continued and the reactor effluent stripped to obtain the resin. The order of polymerization may be reversed.
