The effect of some antioxidants on radiation crosslinking of polyethylene-vinylacetate

The electron beam induced crosslinking of polyethylene-vinylacetate in the presence of two selected antioxidants -quinoline and hydrazine type - was studied and compared with investigations of the equivalent low density polyethylene compounds. The effect of vinylacetate groups on crosslinking efficiency of the mentioned copolymer was studied, too. It is shown that both antioxidants used decreased crosslinking efficiency of irradiated polyethylene-vinylacetate compounds. (author)
