Abstract
An article, such as a lens article () containing a first component, e.g., a filter ('), or component thereof, having a minimum degradation temperature, and a second component, e.g., a substrate (′), comprising a blend of first and second thermoplastic polymers. The first polymer, which has a glass transition temperature higher than the minimum degradation temperature of the first component, is selected based upon its ability to provide the article with one or more desirable characteristics. The second polymer is blended with the first polymer in a predetermined amount that provides the blend with an adjusted glass transition temperature lower than the minimum degradation temperature of the first component so that the first and second components can be heat processed together at a temperature greater than or equal to the adjusted glass transition temperature but below the minimum degradation temperature.
