摘要： The object of the present invention is to produce a polymer, which is free from the troubles of the coloration and the decrease in the mechanical properties of molded articles (films, etc.), crosslinkage failure, migration (stain) or the like, by the living radical polymerization method wherein the content of impurities consisting of a transition metal and its ligand employed as a polymerization activator is reduced. A process for producing a polymer is described, comprising: a) the step of performing a polymerization reaction by using a monomer, a transition metal and its ligand and a polymerization initiator to form a polymer; and b) the step of eliminating the transition metal and its ligand contained in the polymer under the condition of a viscosity of 100 Pa·s or below, wherein the step b comprises: b1) the former step of eliminating the transition metal and its ligand insoluble in the polymer; and b2) the latter step of eliminating the transition metal and its ligand dissolved in the polymer.

摘要： An ultraviolet crosslinking pressure-sensitive adhesive composition showing good pressure-sensitive adhesive characteristics is obtained by using a block copolymer of styrenic polymer component and acrylic polymer component. The pressure-sensitive adhesive composition is produced by conducting living radical polymerization of styrenic monomer and acrylic monomer in a proper order in the presence of a transition metal and its ligand using a polymerization initiator to obtain a block copolymer (a) wherein at least one styrenic polymer block A and at least one acrylic polymer block B are bound to each other and mixing it with a trichloromethyl group-containing triazine derivative (b) or, alternatively, to obtain a block copolymer (a) which contains carboxy precursor groups in the acrylic polymer block B, and converting the precursor groups to carboxyl groups, before or after mixing with the component (b), by heat-treating in the presence of an acid catalyst.
