A thermoplastic crosslinked rubber composition comprising (A) from 1 to 99 parts by weight of a hydrogenated rubber obtained by hydrogenating not less than 50% of total double bonds of at least one homopolymer rubber of a conjugated diene type monomer or a random copolymer rubber consisting of a conjugated diene type monomer unit and an aromatic vinyl monomer unit and (B) from 1 to 99 parts by weight of an olefinic thermoplastic resin, total amount of (A) and (B) being 100 parts by weight, said (A) being partially or completely crosslinked, wherein said (A) is crystalline rubber, having a crystallization temperature in a range of from &#x2212;50 to 70&#xb0; C. and a heat quantity of crystallization at peak in a range of from 3 to 100 J/g in differential scanning calorimetry (DSC method).

Thermoplastic crosslinked rubber composition

A thermoplastic crosslinked rubber composition comprising (A) from 1 to 99 parts by weight of a hydrogenated rubber obtained by hydrogenating not less than 50% of total double bonds of at least one homopolymer rubber of a conjugated diene type monomer or a random copolymer rubber consisting of a conjugated diene type monomer unit and an aromatic vinyl monomer unit and (B) from 1 to 99 parts by weight of an olefinic thermoplastic resin, total amount of (A) and (B) being 100 parts by weight, said (A) being partially or completely crosslinked, wherein said (A) is crystalline rubber, having a crystallization temperature in a range of from &minus;50 to 70&deg; C. and a heat quantity of crystallization at peak in a range of from 3 to 100 J/g in differential scanning calorimetry (DSC method).

A hot-melt pressure-sensitive adhesive composition comprising (a) 100 parts by weight of a specific grafted block copolymer material formed by the graft reaction of at least one block copolymer comprising at least one polybutadiene or polyisoprene block and at least two polystyrene blocks with at least one unsaturated carboxylic acid monomer and/or derivative monomer thereof and (b) 50 to 250 parts by weight of a specific tackifier mixture consisting of a tackifier S comprising at least 50% by weight of a terpene resin having a softening point of 60.degree. C. or more and a tackifier L comprising at least 50% by weight of a terpene resin having a softening point of 30.degree. C. or less and having an S/L mixing weight ratio of 9/1 to 3/7, and optionally 1 to 50 parts by weight of a softening agent has been found to be excellent in holding power especially for paper.
