AQUEOUS ADHESIVE COMPOSITIONS FOR USE IN BINDING BOOKS

摘要

Adhesive compositions which are free of humectants are prepared from vinyl acetate homopolymer and/or ethylene vinyl acetate copolymer lattices which have been prepared by emulsion polymerization methods which utilize dextrin as the protective colloid. The adhesives are characterized by superior adhesion in case making and are prepared by post-adding specific amounts dextrin and a borax to the dextrin-emulsified polymer latex.
