| Abstract: | Acrylate elastomer (ACE) synthesized ourselves was mixed with antioxidative and UV stabilizer into polyoxymethylene (POM) matrices to investigate the effects of the ACE phase on the mechanical properties and UV stability of POM. For comparison, POM blended with same amount of TPU instead of ACE was used. Dispersion of the elastomer particles in POM matrices was investigated using SEM micrograph. Crystallinities of the specimen before and after UV ageing were also measured. The surface molecular weight and the mechanical properties of modified POM after UV ageing were determined. The result showed that excellent mechanical properties of the POM composites after UV‐irradiation could be obtained by blending with ACE. |
