Abstract
Hot melt compositions comprising a mixture of an adhesive ethylene-vinyl acetate copolymer having a melt index of 700 to 10000 and containing from 9 to 40% vinyl acetate in combination with an olefin rubber exhibit excellent adhesive properties. The resulting blends have good elevated temperature resistance; outstanding low temperature flexibility, excellent adhesion to a wide variety of surfaces and markedly reduced melt viscosities at the application temperature.
