Abstract
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.
