Abstract:
In biodegradable resin products consisting essentially of a polymeric resin selected from the group consisting of polyethylene resins, starch, polyesters selected from the group consisting of polylactic acid or polycaprolactone, and copolymer blends of reactant mixtures of butanediol, adipic acid, succinic acid, and terephthalic acid, and wherein a particulate vapor phase corrosion inhibitor is dispersed within the resin product, the combination being characterized in that:(a) said vapor phase corrosion inhibitor is selected from amine salts, ammonium benzoate, triazole derivatives, alkali dibasic acid salts, alkali nitrites, tall oil imidazolines, alkali metal molybdates, and mixtures thereof, and is present in an amount ranging up to 25% by weight of the polymeric resin;(b) said biodegradable resin products being further blended with a suitable polymeric resin to provide finished products containing between 1% and 3% vapor phase corrosion inhibitor.
