<p>PURPOSE:To provide a hot-melt compsn. having excellent adhesiveness, containing a copolymer resin derived from a five-membered ring compd. having conjugated double bonds and a dimer or a trimer of a diene, and an ethylene copolymer or waxes. CONSTITUTION:20-38pts.wt. five-membered ring compd. of the formula (wherein H is hydrogen; R is 1-3C alkyl; m, n are 0, 1 or more; m+n=6) and/or a Diels- Alder adduct of the five-membered ring compd. (component A) is copolymerized with 80-62pts.wt. dimer or trimer of a diene selected from said five-membered ring compd., isoprene and piperylene (with the exception of the compd. included in the component A) (component B) to produce a copolymer resin (I) which is then hydrogenated to produce a hydrogenated resin (II) having a softening point of 60-130 deg.C. There is provided a compsn. containing the above hydrogenated resin (a) and an ethylene copolymer and/or waxes (b).</p> |
