Abstract
The invention relates to novel cinnamamides, a process for their manufacture and their use as UV absorbers. The cinnamamides of the invention may be used as UV absorbers in a variety of engineered resins such as polyamides (especially nylon 6 and 6,6), polycarbonates, polyacetals, polysulfones, polyimides, polyaryletherketones, and polyesters, (especially PET and PBT), as well as, other polymers such as polyvinylchloride and polyolefins (polyethylenes and polypropylenes).
