| 中文摘要 | the anti-aging performance of blends of polystyrene (ps), styrene-butadiene triblock copolymers (sbs), and ps/styrene-butadiene (sb)-4a (carm star se block copolymer) has been studied by means of c-13 nmr techniques. it is found that the anti-aging performance of these kinds of blends largely depends on their miscibility with ps of different molecular weight m(ps). the larger the quantities of ps solubilized in polybutadiene (pbd) domains, the better the anti-aging performance of the blends. it is also found that the anti-aging performance of these blends has dependence on molecular architectures of the se block copolymers. for the aged blends, the double bonds of pbd were broken, meanwhile serious cross-linking networks formed in the blends. the proposed anti-aging mechanism is that the ps solubilized in pbd domains can efficiently prevent oxygen molecules from diffusing into pbd domains, therefore, successfully stop the oxidative process of pbd. |
