Abstract:
1. A method of making a thermoformable article comprising: forming a light-stabilized polyamide polymer having from about 2.5 to about 15.0 weight percent of one or more light-stabilizing moieties covalently bonded along the polyamide polymer chain, wherein the weight of the one or more light-stabilizing moieties is based on a total weight of polymer-forming components; blending the light-stabilized polyamide polymer with one or more additional polymers, which are substantially free of light-stabilizing moieties, to form a polymer blend; and shaping the polymer blend to form a light-stabilized polymer blend having a weight percent of one or more light-stabilizing moieties covalently bonded along one or more polyamide polymer chains of less than about 2.0 weight percent, based on the weight of the polymer blend.
