    • Olefin polymer compositions comprise an antistatic agent of formula R(OCHR1CH2)nOCH2COOH where R is an aliphatic or cycloaliphatic radical of 1 to 20 C atoms or an aliphatic-aromatic radical of 1 to 20 C atoms in the aliphatic part, R1 is hydrogen or methyl and n is 1 to 40. Specified polymers are polyethylene, polypropylene, ethylene/propylene copolymers, and copolymers of one or more olefins with other comonomers. The compositions may be in the form of films, fibres or other shaped articles, and examples describe compositions of polyethylene and polypropylene and antistatic agents in which R1 is hydrogen and R is derived from commercial lauryl alcohol, oleyl alcohol, stearyl alcohol, nonylphenol, ethyl alcohol, hexyl alcohol and mixtures of lauryl and myristyl alcohols.ALSO:Articles such as films made of olefin polymer compositions may be rendered antistatic by applying to the surfaces thereof an antistatic agent of formula R(OCHR1CH2)n OCH2COOH where R is an aliphatic or cycloaliphatic radical having up to 20 carbon atoms or an aliphatic aromatic radical having up to 20 carbon atoms in the aliphatic part, R1 is hydrogen or methyl and n is 1 to 40. Specified polymers are polyethylene, polypropylene, ethylene/propylene copolymers, and copolymers of one or more olefins with other monomers. Exemplified antistatic agents are those in which R1 is hydrogen and R is derived from commercial lauryl alcohol, oleyl alcohol, stearyl alcohol, nonylphenol, ethyl alcohol, hexyl alcohol and mixtures of lauryl and myristyl alcohol.
