Weatherable vinyl polymer compositions |
摘要 |
The invention relates to a vinyl halide polymer composition suitable for outdoor use in the sunlight. The change in color as measured by DELTA E in articles made from the polymeric composition is found to be substantially lower than other compositions. The lower DELTA E provides a measurement for improved weatherability of the compositions in such applications as housing siding, window profiles, shutters and roof vents.
