Anti-fogging films based on ethylene copolymer compositions

An article comprising an antifogging composition comprising:

• 1) a copolymer comprising copolymerized units of ethylene and copolymerized units of a comonomer providing an amine-reactive site comprising an anhydride group, a vicinal pair of carboxylic groups or a carboxylic group adjacent to an alkoxycarbonyl group, wherein the alkoxy group contains up to 20 carbon atoms, and optionally copolymerized units of a third comonomer, wherein the amine-reactive site is present in the copolymer in an amount of from 3 to 25 weight %;
• in an amount of about 25 to 95 weight % of the combination of 1) and 2);
• and
• 2) a short chain polymer having from about 5 to 50 repeat units and containing one primary amine active amine site, the remainder of the side chain polymer being substantially unreactive with the amine-reactive sites of the copolymer of (b) and comprising propylene oxide, ethylene oxide, or mixture thereof;
• and the side chain polymer content ranges from about 5 to 75 weight % of the combination of 1) and 2);
• and
• 3) optionally from 0 to 50 weight %, based on the combination of 1), 2) and 3), of polyethylene homopolymers, polyethylene copolymers, polypropylene homopolymers or polypropylene copolymers or ethylene copolymer, different from the copolymer of 1), comprising copolymerized units of ethylene and copolymerized units of a polar comonomer selected from vinyl acetate, alkyl methacrylate, alkyl acrylate, carbon monoxide or mixtures thereof, wherein the polar comonomer is present in the copolymer in an amount from about 6 to about 40 weight %.
