Claims
- 1. A thermoplastic crosslinked rubber composition obtained by crosslinking (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, wherein said (A) is crystalline rubber, having a crystallization temperature in a range of from −50 to 70° 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).
- 2. A thermoplastic crosslinked rubber composition comprising (A) from 1 to 99 parts by weight of at least one homopolymer rubber of a conjugated diene type monomer or a random or block copolymer rubber consisting of a conjugated diene type monomer unit and an aromatic vinyl monomer unit or a hydrogenated rubber thereof and (B) from 1 to 99 parts by weight of a non-olefinic thermoplastic resin or a mixture of an olefinic thermoplastic resin and a non-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 a non-crystalline rubber or a crystalline rubber.
- 3. A thermoplastic crosslinked rubber composition obtained by crosslinking (A) from 1 to 99 parts by weight of at least one homopolymer rubber of a conjugated diene type monomer or a random or block copolymer rubber consisting of a conjugated diene type monomer unit and an aromatic vinyl monomer unit or a hydrogenated rubber thereof and (B) from 1 to 99 parts by weight of a non-olefinic thermoplastic resin or a mixture of an olefinic thermoplastic resin and a non-olefinic thermoplastic resin, total amount of (A) and (B) being 100 parts by weight, wherein said (A) is a non-crystalline rubber or a crystalline rubber.
- 4. The thermoplastic crosslinked rubber composition according to claim 2 or 3, wherein in the case of said (A) being a crystalline rubber, said (A) has a crystallization temperature in a range of from −50 to 70° 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).
- 5. The thermoplastic crosslinked rubber composition according to claim 2 or 3, wherein (B) is a mixture of an olefinic thermoplastic resin and a non-olefinic thermoplastic resin, and amount of a non-olefinic thermoplastic resin in said mixture is not less than 40% by weight.
- 6. The thermoplastic crosslinked rubber composition according to claim 2 or 3, wherein (B) is a mixture of an olefinic thermoplastic resin and a non-olefinic thermoplastic resin, and amount of a non-olefinic thermoplastic resin in said mixture is not less than 1% by weight and less than 40% by weight.
- 7. The thermoplastic crosslinked rubber composition according to claim 2 or 3, wherein the hydrogenated rubber of (A) is a polymer obtained by hydrogenating not less than 50% of total double bonds of the homopolymer rubber or the copolymer rubber.
- 8. The thermoplastic crosslinked rubber composition according to claim 2 or 3, wherein said non-olefinic thermoplastic resin is a styrene-based resin.
