Abstract
A method of stabilizing a normally solid polyalkylene carbonate resin against thermal and hydrolytic decomposition, including the step of adding a cyclic amine selected from the group consisting of imidazole and 2-ethyl 4-methylimidazole at a wt. % of 5 to 45% of the normally solid polycarbonate resin. And, a method of producing tough coatings with excellent adhesion to both ferrous and non-ferrous metals, including the steps of: a) dissolving polyalkylene carbonate resin and a cyclic amine selected from the group of consisting of imidazole and 2-ethyl 4-methylimidazole at a wt. % of 5 to 45% of the normally solid polycarbonate resin in a solvent selected from the group consisting of methyl ethyl ketone and propylene glycol mono methyl ether acetate by mechanical mixing so as to form a solution; b) coating the ferrous or non-ferrous metals with the solution so as to form a coated metal; c) air drying the coated metal to evaporate the solvent so as to form an air-dried coated metal; and, d) curing the air-dried coated metal for a time selected from the group consisting of at least 12 hours at ambient temperature and 15 minutes at 150° C.
