Abstract:
A hot melt composition comprising:(a) an ethylene copolymer resin: 100 weight parts;(b) a modified aromatic petroleum resin having a weight-average molecular weight in the range of 500 to 2000 and produced by the copolymerization of components (1) through (3) below using a Friedel-Crafts catalyst: 50 to 150 weight parts;(1) a polymerizable component of a thermal cracked oil fraction obtained by the thermal cracking of petroleum hydrocarbons, said fraction being composed primarily of components having boiling points in the range of 140.degree. C. to 220.degree. C. and containing vinyltoluene at a content of 10% by weight or above and below 60% by weight and indene at a content of 10 to 80% by weight: 100 weight parts,(2) a turpentine oil having a diene value in the range of 15 to 60 cg/g: 10 to 40 weight parts, and(3) a phenol, alkyl substituted phenol, or mixtures thereof: 1 to 15 weight parts; and(c) a wax: 10 to 100 weight parts.
