Abstract:
1. An adhesive composition comprising a crystalline polymer and a tackifying polymer compatible with said crystalline polymer at a temperature higher than the melting point of said crystalline polymer, characterized in that said crystalline polymer comprises polyol units formed from a crystalline polyol as repeating units in the molecule units, wherein the polyol units include an alkylene backbone with 4 to 6 carbon atoms, said tackifying polymer has an alkyl group with 4 to 8 carbon atoms and a carboxyl group in the molecule, a content of the monomeric units having said alkyl group with 4 to 8 carbon atoms (repeating units derived from a starting monomer having said alkyl group) is 60 to 99 mole % of the whole monomeric units of said tackifying polymer, and said alkyl group includes a butyl group.
