摘要:
A process and an apparatus for molding, in which a molten thermoplastic resin is firmly fitted onto a molding surface (30) of a mold under a pressure lower than or equal to 100 kg/cm 2 and is cured to obtain a molded product. The molding apparatus has a mold main body (4), and a mold body (3) on which the molding surface (90) is defined. The mold body (3) is supported relative to the mold main body (4) with maintaining a space (B) on the back side (31) of the molding surface (30) in a heat insulative manner by a supporting member (1) which includes at least a heat insulative supporting member having a thermal conductivity of 0.001 to 1 Kcal/mh °C and a longitudinal elastic modulus of 0.01 to 10 kg/cm 2 . In the space (B), a heating fluid for heating the molding surface (30) from the bask side to a temperature higher than or equal to Vicat softening temperate (T) °C of the thermoplastic resin and a cooling fluid for cooling the molding surface (30) from the back side to a temperature lower than or equal to (Vicat softening temperature (T) of the thermoplastic resin - 10) °C are supplied.

摘要:
A thermoplastic elastomer composition comprising: 99-1 parts by weight of (i) a hydrogenated diene polymer which is a hydrogenation product of a straight or branched chain block copolymer consisting of (C) a polybutadiene block segment having a 1,2-vinyl content of not more than 20% and (D) a block segment which is a polybutadiene or an alkenyl aromatic compound-butadiene copolymer, the butadiene portion of which has a 1,2-vinyl content of 25-95%, the block structure of said straight or branched chain block copolymer being represented by the formula, C-(D-C) n or (C-D) m in which C means the above-mentioned polybutadiene block segment (C), D means the above-mentioned block segment (D), n means an integer of 1 or more and m means an integer of 2 or more, at least 90% of the double bond in the butadiene portion of the straight or branched chain block copolymer having been hydrogenated, or (i′) a modified hydrogenated diene polymer in which 0.01 to 10 mole % of at least one functional group selected from the group consisting of carboxyl group, acid anhydride group, hydroxyl group, epoxy group, halogen atom and amino group is added to the hydrogenated diene polymer (i), and 1-99 parts by eight of at least one member selected from the group consisting of a thermoplastic resin and a rubbery polymer. The above thermopalstic elastomer composition has properties comparable to a vulcanized rubber and is useful in various industrial parts.
