Abstract: The vibration damper material comprises a laminate of a viscoelastic layer and a hardenable pressure sensitive adhesive layer, and a release liner applied onto the hardenable pressure sensitive adhesive layer. The viscoelastic layer is intended to form a vibration damping layer, and contains a viscoelastic material mainly comprised of unvulcanized rubber to which a vulcanizing agent (crosslinking agent) has been added. The hardenable pressure sensitive adhesive layer comprises a hardenable pressure sensitive adhesive which has adhesive properties in the uncured state but has a strong adhesive strength when it is cured by heating, irradiation with light or by being blocked from air for example. This hardenable pressure sensitive adhesive layer contains a sticking polymer, a reactive oligomer and a polymerization initiator. The release liner which is utilized has a silicone layer formed on the surface of a base material thereof.

Abstract: A vibration damper material 1 composed of a laminated sheet having a base stock layer 3, a resilient layer 4, an primer layer 5, an organic component barrier layer 6 and an adhesive layer 7 successively laminated in that order from one to the other side thereof, and a release liner 8 stuck on the adhesive layer 7. The resilient layer 4 is constituted by a resilient material containing a vehicle consisting of a member or a mixture of two or more members selected from the group of asphalt, rubber, synthetic resins and cellulose derivatives, synthetic resin powder, and an elastic material having an elongation rate of 500% or higher. The organic component barrier layer functions to block permeation therethrough of organic components such as tar and oil components which would otherwise tend to migrate into the adhesive layer from the resilient layer.

Abstract: A pressure sensitive adhesive sheet comprising a substrate and an adhesive composition which is coated on the surface of the substrate. The main components of the adhesive composition are (a) a copolymer comprising monomeric units of an acrylic ester, (b) monomeric units of a polar acrylic compound, (c) monomeric units of a high glass transition temperature (Tg) macromonomer having a Tg of 20.degree. C. or above, (d) monomeric units of a low Tg macromonomer having a Tg of below 20.degree. C. and (e) monomeric units of an oligomer having telechelic thiol functional groups. The pressure sensitive adhesive sheet has excellent adhesive strength, resistance against formation of blisters and removability upon heating.

Abstract: A membrane for the separation of an organic solvent from a water-organic solvent mixture has a polymeric membrane of a copolymer consisting essentially of an .alpha., .beta.-unsaturated carbonyl compound as a main monomer. The .alpha., .beta.-unsaturated carbonyl compound includes an acrylic acid ester or a methacrylic acid ester. The polymeric membrane has a crosslinked structure. The polymeric membrane is carried on a support member in the form of a flat membrane, a pipe or a hollow fiber. The polymeric member includes particles therein. The polymeric membrane is sandwiched by the support members to form a composite-type separation membrane. The composite-type separation membrane is modulated.
