    摘要： A rubber composition obtained by

    (a) mixing at least one low air permeable rubber having a vulcanisable functional group and a curing agent, which can vulcanise the low air permeable rubber having the vulcanisable functional group, at a temperature within a range where the low air permeable rubber having vulcanisable functional group is not vulcanised, and
    (b) blending 25 to 100 parts by weight of at least one rubber having a vulcanisable carbon-carbon double bond per 100 parts by weight of the low air permeable rubber having the vulcanisable functional group with the mixed product, mixing at a temperature within a range where the low air permeable rubber having vulcanisable functional group can be vulcanised to selectively vulcanise the low air permeable rubber having vulcanisable functional group.

    The rubber composition of the present invention is superior in adhesion property by vulcanisation to other diene rubber compositions and, from the rubber composition, the rubber moulded article not inferior in low air permeability can be obtained.

    摘要： Provided are methods for surface-modifying a rubber vulcanizate or a thermoplastic elastomer, the methods forming a surface with a chemically fixed lubricant instead of resin coating which has drawbacks, such as that the coating is, for example, removed or peeled during the movement within a vessel, whereby the lubricity is reduced. The present invention relates to a method for surface-modifying an object of a rubber vulcanizate or a thermoplastic elastomer, the method including step 1 of forming polymerization initiation points on a surface of the object, and step 2 of radically polymerizing a deliquescent monomer starting from the polymerization initiation points by irradiation with ultraviolet light having a wavelength within the range of 300 to 400 nm, to grow polymer chains on the surface of the object.

    摘要： The present invention aims to provide a method for surface-modifying a rubber vulcanizate or a thermoplastic elastomer, which is capable of cost-effectively imparting a variety of functions, such as sliding properties and biocompatibility, according to the applications. The present invention relates to a surface modification method for surface-modifying an object of a rubber vulcanizate or a thermoplastic elastomer, the method including: step 1 of forming polymerization initiation points A on a surface of the object; step 2 of radically polymerizing a non-functional monomer, starting from the polymerization initiation points A, to grow non-functional polymer chains; step 3 of forming polymerization initiation points B on the surface of the object where the non-functional polymer chains are formed; and step 4 of radically polymerizing a functional monomer, starting from the polymerization initiation points B, to grow functional polymer chains.

    摘要： The present invention aims to provide a dynamically-crosslinked thermoplastic elastomer composition that can provide a molded product exhibiting low compression set especially in the case of being cooled under stress. The present invention relates to a thermoplastic elastomer composition, including a dynamically-crosslinked butyl rubber and a thermoplastic resin; and having a thermoplastic resin content of not more than 8% by mass. The dynamically-crosslinked butyl rubber is preferably a halogen-containing butyl rubber.
