<p>A method of reducing the color of a hot melt adhesive formulation comprising a block polymer of a conjugated diene and a vinyl aromatic hydrocarbon which comprises adding to the formulation an amount of 4,4-bis(alpha,alpha-dimethylbenzyl)diphenylamine sufficient to reduce color formation. This method is especially effective for epoxy resin coupled polymers and sequentially polymerized polymers.</p> |
