Abstract
Hot melt adhesive compositions are provided which contain (a) about 10-30 weight % of an alkenyl succinic anhydride, (b) about 20-60 weight % of an ethylene copolymer, and (c) about 10-40 weight % of a tackifying resin which is an aliphatic hydrocarbon resin.
Claims9
A hot melt adhesive composition consisting essentially of:
- (a) 10-30 weight % of an alkenyl succinic anhydride,
- (b) 20-60 weight % of an ethylene copolymer, and
- (c) 10-40 weight % of a tackifying resin;
- said alkenyl succinic anhydride having the structure:
- ##STR2## where R is an alkyl group containing at least about 15 carbon atoms;
- said ethylene copolymer having polymerized therein at least 40 weight % polymerized ethylene and the balance one or more polymerized monomers from the group consisting of vinyl acetate, acrylic and methacrylic acid and alkyl esters of acrylic and methacrylic acid;
- and said tackifying resin being an aliphatic hydrocarbon resin having a Ring and Ball softening point of about 10.degree.-135.degree. C.
