There are provided a modified liquid diene rubber that can be used for a curable resin composition and a resin composition containing the modified liquid diene rubber. The curable resin composition containing the modified liquid diene rubber has a much higher curing rate than that in the related art, and the resulting cured product has excellent mechanical properties, transparency, and heat resistance. Produced are a modified liquid diene rubber and a resin composition containing the modified liquid diene rubber. The modified liquid diene rubber includes a modifying group (p) partly containing a (meth)acryloyl group therein and a monomer unit (a1) derived from a conjugated diene compound. A carbon-carbon double bond derived from the conjugated diene compound has a hydrogenation rate of 30 to 95 mol %, and the modifying group (p) has a functional group equivalent weight of 700 to 20,000 g/eq.

The present invention provides a pressure-sensitive adhesive composition having an excellent adhesive force when bonding to an adherend, having excellent peelability when subjected to batch heat treatments at a high temperature, and having both a high initial adhesive force and a low post-heating adhesive force. The pressure-sensitive adhesive composition according to the present invention contains: a material having a radically polymerizable functional group; and a thermal polymerization initiator that generates a radical, in which a content of the thermal polymerization initiator is 1.2 to 10 parts by mass with respect to 100 parts by mass of all components excluding the thermal polymerization initiator.

Modification of functional groups along a polymer backbone to render the groups activatable upon exposure to actinic radiation is described. The polymers are typically controlled architecture polymers. Also described are adhesives containing the modified architectured polymers and related methods of use.
