Polyurethane—poly mechanical response

Dynamic Mechanical Response of In Situ Polyurethane—Poly (methyl methacrylate) Interpenetrating Polymer Networks... [Pg.445]

The response of polyurethanes to thermally activated autoxidation depends on polymer structure. In general, polyurethane degradation by this mechanism is suppressed by the addition of antioxidant to the polymer. But in one study with a poly (ether-urethane) this was not true. Ultraviolet initiated autoxidation is suppressed by a suitable screen (e.g., carbon black, titanium dioxide) or a combination of antioxidant and ultraviolet absorber. Irganox 1010 and Tinuvin P (Ciba-Geigy) are particularly suitable antioxidant and ultraviolet absorbers, respectively, for polyurethanes. The polymer chemist can tailor polyurethane structures with enhanced resistance to ultraviolet-initiated autoxidation. [Pg.374]
