STARCH-ACRYLIC COPOLYMER USEFUL FOR PAPER SURFACE SIZING AND METHOD FOR PREPARING SAME, COMPOSITION COMPRISING COPOLYMER FOR PAPER SURFACE SIZING, AND PAPER HAVING SURFACE TREATED WITH SAME COMPOSITION
STARCH-ACRYLIC COPOLYMER USEFUL FOR PAPER SURFACE SIZING AND METHOD FOR PREPARING SAME, COMPOSITION COMPRISING COPOLYMER FOR PAPER SURFACE SIZING, AND PAPER HAVING SURFACE TREATED WITH SAME COMPOSITION
The present invention relates to paper surface sizing. More particularly, the present invention relates to a starch-acrylic copolymer obtained by polymerizing dextrin, positive starch and an acrylic monomer in the presence of a base, a method for preparing the same, a composition comprising the copolymer for paper surface sizing, a method for treating a paper surface with the composition, and paper treated thereby. When carrying out paper surface sizing, treatment of a paper surface with the composition comprising the starch-acrylic copolymer according to the present invention can provide higher paper strength even with a reduced amount of starch as compared to the related art. In addition, it is possible to reduce the energy requirement for drying paper by virtue of a decrease in use of starch.;COPYRIGHT KIPO 2017
