Abstract

PURPOSE: The titled adhesive, suitable for bookbinding, having improved heat- and moisture-resistant adhesiveness and cold resistance, and prepared by partly saponifying a specific copolymer of a vinyl ester of a saturated branched fatty acid, allyl acetate and vinyl acetate in a specific proportion.
CONSTITUTION: (A) 0.5W10pts.wt. a vinyl ester of a saturated branched fatty acid, preferably the total carbon number of the alkyl group being 6W12, of formula I (R1, R2 and R3 are alkyl groups) is copolymerized with (B) 1W40pts.wt. allyl acetate and (C) 100pts.wt. vinyl acetate to give a copolymer, e.g. having the repeating unit of formula II, with an intrinsic viscosity of 0.09W0.35 (measured at 30°C in acetone solvent in concentration units of g/100ml). preferably, 50W85mol% of the components (B) and (C) in the copolymer is partly saponified to afford the aimed adhesive having the repeating unit of formula III.
EFFECT: No trouble due to adhesives will occur in recovering as a waste paper after use for a back lining in bookbinding or labels.
