Abstract
Alkali-soluble hot melt adhesive compositions are provided which contain (a) about 10-40 weight % of an alkenyl succinic anhydride, (b) a carboxyl group containing ethylene copolymer, and (c) about 10-50 weight % of rosin.
Claims6
An alkali-soluble hot melt adhesive composition consisting essentially of:
- (a) 10-30 weight % of an alkenyl succinic anhydride,
- (b) 30-50 weight % of an ethylene polymer having an acid number of about 0.25-30.0, and
- (c) 10-50 weight % of a rosin material selected from natural rosins, hydrogenated rosins and isomerized rosins;
- said alkenyl succinic anhydride having been prepared by heating a high molecular weight alpha-olefin containing 30 or more carbon atoms with maleic anhydride.
