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： 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： 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.
