Abstract: A pressure sensitive adhesive is obtained by polymerizing a mixture containing: (1) 100 mass parts of (meth)acrylic monomer comprising 98-50 mass parts of a first monomer selected from an aliphatic (meth)alkyl acrylate having a carbon number of 4-6 and an aliphatic (meth)alkyl acrylate having a carbon number of 7-12, wherein the glass transition temperature of a homo-polymer thereof is ?25 degrees C. or less; and 2-50 mass parts of a second monomer comprising one or more selected from the group consisting of: an amide group-containing ethylenic unsaturated copolymerizing monomer, a carboxylic group-containing ethylenic unsaturated copolymerizing monomer, an amino group-containing ethylenic unsaturated copolymerizing monomer, a non-tertial alkyl(meth)acrylate wherein the glass transition temperature of a homo-polymer thereof is ?25 degrees C.

Abstract: A cross-linked foamed pressure sensitive adhesive having excellent stress relaxing property, restoration property and solvent resistance brought forth by uniform and sufficient cross-linking and foaming irrespective of transmissibility of ultraviolet rays and electron beams to components, and free from drawbacks inherent to low molecular weight acrylic copolymers. A cross-linked foamed pressure sensitive adhesive having restoration property, prepared by heating a heat cross-linkable and heat foamable composition containing a tacky polymer having a molecular weight of at least 100,000, a heat cross-linking agent and a heat foaming agent to cause cross-linking and foaming.

Abstract: A heat-curable molding material pellet comprising a heat-curable epoxy-containing material, a thermoplastic component and a curing agent for the epoxy-containing material, wherein the pellet has a multilayer structure comprising a core containing a first heat-curable component and a sheath containing a second heat-curable component, disposed in the periphery of the core.

Abstract: To provide a flange section seal material that allows satisfactory and easy sealing of flange sections for vehicles. A flange section seal material comprising at least two layers for sealing of the flange section of metal panels for a vehicle, the flange section seal material being characterized by having an inner layer containing a hot-melt/fluidizable thermosetting resin with a curing temperature of 80-200° C., and an outer layer which exhibits no significant fluidizing shape change at 80-200° C.
