ABSTRACT:
A thermoplastic synthetic resin, especially high-density polyethylene, has its diffusion coefficient especially for hydrocarbons, reduced by the addition of 2 to 8% by weight of an additive consisting essentially of at least one phenoxy resin, and at least one further component selected from the group which consists of at least one radical forming agent and at least one graft coploymerization catalyst, and optional quantities of an antioxidant selected from the group which consists of at least one phenolic antioxidant, at least one phosphitic antioxidant and mixtures thereof, at least one organosilane ester, at least one UV stabilizer, at least one antistatic composition, and polypropylene.
