Reaction of a carboxylic acid anhydride, and by photochemical cross-linking subsequent to it, containing a vinyl alcohol group, modification of the polymer was acetalized

摘要

A portion of the vinyl alcohol groups, the invention relates to modified polymers containing reaction of olefinically unsaturated carboxylic acid anhydride of 1, and is obtained by photochemical crosslinking of the reaction product subsequently, the vinyl alcohol group at least.
