Abstract
Conditions of synthesis of water-soluble derivatives of epichlorhydrin e through ionic copolymerization with maleic and phthalic-anhydride in the presence of a special initiator have been found out. Synthesized copolymers with molecular weight from 3000 to 12000 do not possess any sizing effect of their own but improve paper strength by 10 divided b y 20%. When used simultaneously with rosin size, they have synergetic effect and impart increased hydrophobicity and higher strength to the paper.
