Abstract
A structural hot melt adhesive of butadiene grafted ethylene-vinyl acetate. The butadiene graft is 1 to 12 percent by weight, preferably 4 to 8 percent by weight. The ethylene/vinyl acetate ratio is about 91/9 to 72/28, preferably about 83/17. Preferably grafting is done at room temperature using radiation. Peel adhesion on various fabric and metal substrates improved over ungrafted control samples from 100 to as much as 1500 percent.
