ABSTRACT:
A method for preparing iodoalkynylcarbamates exhibiting little or no discoloration or yellowing when incorporated into coating compositions, such as paint compositions, and exposed to sunlight. An alkynol is reacted with freshly distilled isocyanate prepared within 24 to 120 hours prior to reaction with the alkynol, and the resulting product is iodinated to form an iodoalkynylcarbamate that exhibits little or no discoloration or yellowing when incorporated into coating compositions, such as paint compositions, and exposed to ultraviolet light.
