For methyl methacrylate-methacrylic acid copolymer colored by laser dyes (Rhodamine 6G and Coumarin 7), the mutual effect of polymeric matrix and dyes on the kinetics of their photochemical aging was studied. Diphenylthiourea ...

The anionic copolymerization of a series of cyclic carbonates with phenylisocyanate is investigated in the presence of sodium caprolactam. The structure of the obtained copolymers is established, and the mechanism of ...
