PURPOSE: To provide tubes for curing the self-peelable rubber which is useful for production of pneumatic tires by admixing a butadiene-acrylonitrile copolymer, an epichlorohydrin polymer or a specific graft copolymer to rubber. CONSTITUTION: A graft copolymer A which is obtained by melt-mixing A1: 100 pts.wt. of brominated p-methylstyrene-isobutylene copolymer, ethylene- propylene terpolymer, hydrogenated polybutadiene and/or hydrogenated styrene- butadiene rubber with A2: 2 to 100 pts. wt. of a polar polymer comprising a variety of polyethers a polyester from a cyclic lactone or a polycarbonate obtained by reaction of phosgene with glycols, under shearing at 50 to 180°C or (B) a butadiene-acrylonitrile copolymer or (C) an epichlorohydrin polymer or copolymer is admixed to a rubber admixture to give a self-peelable tube or sleeve for curing which is useful for production of pneumatic tires.

POLY@(3754/24)METALLIC CARBOXYLATE) GRAFT RUBBER HAVING HIGH MODULUS

Номер: JP0006206907A
Автор: UIRIAMU ERU HAAGENROZAA, FUREDERIKU JIEI RABAGUNANI, JIYON EMU DOSHIYAKU
Принадлежит:

PURPOSE: To obtain a polymer, composed of a main chain of an unsaturated hydrocarbon rubber in which a polymerized metallic unsaturated carboxylate is grafted in a pendant state and capable of providing odorless products such as tires manifesting high-modulus properties in a sulfur-cured state. CONSTITUTION: This graft copolymer is composed of a main chain of an unsaturated hydrocarbon rubber in which a polymerized metallic unsaturated carboxylate is grafted in a pendant state. The graft copolymer is obtained by dissolving the unsaturated hydrocarbon rubber in a solvent, providing a rubber solution, then adding a metallic salt of an unsaturated carboxylic acid to the resultant solution, adding a free radical initiator thereto and heating the produced reactional product at about 40-150°C temperature for about 0.1-100hr. A polymer of a diene or terpolymer of EPDM is used as the unsaturated hydrocarbon. COPYRIGHT: (C)1994,JPO&Japio ...

PURPOSE: To obtain a sulfur-vulcanizable rubber compd. having a high modulus and a low hysteresis and giving a flat-running tire by compounding a specific diene rubber compsn. with specified amts. of a reinforcing filter and sulfur. CONSTITUTION: A sulfur-vulcanizable rubber compd. having a high modulus and a low hysteresis is prepd. by compounding 100 pts.wt. diene rubber compsn. with about 50-70 pts.wt. reinforcing filler and at least about 4 pts.wt. sulfur. The diene rubber comps. comprises about 25-55 pts.wt. polysoprene and about 75-45 pts. wt. polybutadiene consisting of a butadiene homopolymer or a polybutadiene contg. up to about 25wt.% styrene-butadiene copolymer provided that at least either the polyisoprene or the polybutadiene has been grafted with a metal salt of an ethylenically α, β-unsatd. carboxylic acid.

PURPOSE: To obtain an elastomer compsn. which has a reduced rolling resistance and good wet traction characteristics and is suitable for producing a tire tread by dispersing oxidized carbon black particles in an elastomeric polymer having functional terminal groups. CONSTITUTION: This compsn. is prepd. by dispersing carbon black particles contg. at least 10wt.% oxidized carbon black in an elastomeric polymer modified by introducing functinal groups into the molecular terminals. The polymer is obtd. by reacting at least one diene monomer or at least one diene monomer and at least one vinylarom. monomer with a compd. having a tin or nitrogen group.

STABILIZATION OF SILOXANE-TERMINATED POLYMER

Номер: JP0010036436A
Автор: HERGENROTHER WILLIAM L, ROGGEMAN DAVID M, GRAVES DANIEL F, STAYER JR MARK L
Принадлежит:

PROBLEM TO BE SOLVED: To stabilize the Mooney viscosity of a siloxane-terminated polymer during desolventation by treating the polymer with a specified viscosity stabilizer in the presence of an inert solvent before it is brought into contact with water. SOLUTION: Before a siloxane-terminated polymer having at least one hydrolyzable substituent at a siloxane terminal group is brought into contact with water, it is treated with a stabilizing amount of a viscosity stabilizer selected among acids, acyl halides, methanesulfonic acid, toluenesulfonic acid, sulfuryl chloride, thionyl chloride, phosgene, carbon dioxide, sulfur dioxide, SOCl and SO2Cl2 in the presence of an inert solvent to stabilize its Mooney viscosity. The solvent which can be desirably used is an aliphatic hydrocarbon, especially hexane. COPYRIGHT: (C)1998,JPO ...
