[Also in Divisions C2 and C3] Mouldings of polyethylene, polypropylene, ethylene/propylene copolymers, polystyrene and vinyl chloride polymers and copolymers are rendered antistatic by treating the surfaces thereof with a solution or dispersion of a fatty acid glyceride containing at least 50 weight per cent of saturated linear C 6-10 fatty acid monoglyceride. Specified glycerides are glyceryl mono octoate, mono caproate, mono oenanthoate, mono pelargonate and mono octoate/ decanoate. In examples sheets of polyvinyl chloride, polyethylene and polystyrene are dipped in (5) ethanol solutions and (6) aqueous dispersions of glyceryl mono octoate/ decanoate.</p> |
