Photochemical properties of oligomeric esters of 2,5-benzophenonedicarboxyl
ic acid and its mixtures with matrix cyclopolyisoprene was studied by integ
rated sensitometry in thin layers. The photosensitizing power of the oligom
er ester of 2,5-benzophenonedicarboxylic acid and 1,4-butylene glycol was s
tudied, and its photochemical activity in the polymer matrix in the presenc
e of a synergist such as N-bromosuccinimide was quantitatively estimated.
