METHOD FOR OBTAINING HOMOGENEOUS GELATINE AND POLYVINYL ALCOHOL COMPOSITION

摘要

FIELD: chemistry.SUBSTANCE: invention relates to chemical industry, in particular, to production of polymer compositions for producing films. Method for producing gelatine and polyvinyl alcohol polymer composition involves mixing of gelatine or its aqueous solution with previously obtained water solution of polyvinyl alcohol, wherein content of residual acetal groups is 10±2.0 wt.% till total concentration of composition not more than 10.0 wt.%.EFFECT: proposed homogeneous polyvinyl alcohol and gelatine composition ensures production of high transparency films.1 cl, 11 ex
