POLYMER PHOTOINITIATORS Russian patent published in 2016 - IPC C08F2/48 C08F2/50 

FIELD: chemistry.

SUBSTANCE: invention relates to photoinitiator, based on polyacryl ether of general formula I R₁(A₁)_r-(R₂(A₂)_m-O)_o-(R₃(A₃)_n-O)_p-R₄(A₄)_s I, where R₂ represents -CH₂CH₂- and R₃ represents -CH₂CH₂-; R₁ represents OH; R₄ represents H; o and p each is a real number in the interval 0-5000 on condition that o+p>0; m and n each is a real number in the interval 0-10 on condition that m+n>0; r and s each is a real number in the interval 0-5; and A₁, A₂, A₃ and A₄ are similar or different benzophenone photoinitiator fragments.

EFFECT: described photoinitiators provide hardening of surrounding matrix, and being polymers are also capable of self-hardening.
