    摘要： An acrylic rubbery polymer having remarkably improved cold resistance can be prepared by modification with an organopolysiloxane by the emulsion copolymerization of a monomeric mixture of two acrylic monomers, of which one is, for example, an alkyl acrylate and the other is an acrylic compound having, in a molecule, at least one ethylenically unsaturated group other than acrylic group in an aqueous emulsion of an organopolysiloxane having a substantial amount of mercapto-substituted monovalent hydrocarbon groups bonded to the silicon atoms.

    摘要： The inventive copolymer composition is satisfactorily curable or vulcanizable into, for example, a rubbery elastomer even by an organic peroxide contained therein as a crosslinking agent. The crosslinkable copolymer comprised therein is a polymer having, in a molecule, at least two monomeric units each having a vinyl-containing organosilicon pendant group represented by the general formula (Vi.sub.m R.sup.1.sub.n SiO).sub.a Vi.sub.b R.sup.2.sub.c Si--, in which Vi is a vinyl group, R.sup.1 is a hydrogen atom or a group selected from the class consisting of monovalent hydrocarbon groups free from aliphatic unsaturation, hydroxy group and hydrolyzable groups excepting halogen atoms, R.sup.2 is a hydrogen atom or a monovalent hydrocarbon group, m is 1, 2 or 3, n is zero, 1 or 2, a is 1, 2 or 3, b is zero, 1 or 2 and c is zero, 1 or 2 with the proviso that a+b=1, 2 or 3 and a+b+c=3. Such a copolymer can be prepared by the copolymerization of a first ordinary ethylenically unsaturated monomer and a second monomer having, simultaneously in a molecule, an ethylenically unsaturated linkage copolymerizable with the first monomer and the vinyl-containing organosilicon group of the above given formula.

    摘要： Proposed is an acrylic rubber-based composition suitable for hot-air vulcanization under normal pressure in a continuous process. The rubber composition comprises, besides an acrylic rubber polymer having, in a molecule, at least two silicon-bonded vinyl groups to serve as the crosslinking sites, reinforcing filler and organic peroxide as a vulcanizing agent, an alkoxy silane compound having a vinyl group or (meth)acryloxy group bonded to the silicon atom, such as vinyl triethoxy silane and 3-methacryloxypropyl trimethoxy silane in a specified amount. This unique ingredient serves as a vulcanization accelerator so that the vulcanization reaction is so rapid as to be freed from foaming of the vulcanizate due to the volatile matters and is complete even in the surface layer without the vulcanization-inhibiting influences by the atmospheric oxygen.

    摘要： An acrylic rubber composition is proposed which is improved in respect of the extrusion-moldability as well as the surface slipperiness of the vulcanized article obtained therefrom. The composition comprises (a) an acrylic rubbery cooplymer which is a copolymer of a (meth)acrylic ester and a coolymerizable organosilicon compound having a silicon-bonded vinyl group in a molecule, (b) a reinforcing filler, (c) a powder of spherical particles having a specified average particle diameter and (d) an organic peroxide as a vulcanizing agent. The composition can be compounded further with a blowing agent to give a foamable rubber composition capable of being vulcanized into a spongy rubber body exhibiting excellent feeling on touch and slipperiness in contact with human skin to be useful, for example, as a material of cosmetic puffs.

    摘要： A train communication system includes a communication relay device that is installed in each vehicle and a communication terminal device that is connected to the communication relay device. The communication relay device acquires vehicle information indicating an in-formation position of a vehicle in which the communication relay device is installed. The communication terminal device refers to a correspondence table that defines a correspondence relationship between vehicle information and communication identification information, and determines communication identification information to be provided to the communication terminal device, based on vehicle information obtained from the communication relay device.
