【Abstract】 The experiment to modify PPR was proceeded in uniform design. On the basis of this design method, the cryogenic impact strength and flexural modulus was analyzed through regression .Through taking advantage of formula obtained from the analysis, the optimal proportion of organomontmorillonite(MMT), dispersion polymer agent(HY-1) in matrix-PPR was confirmed and PPR composite with the cryogenic impact strength improved greatly the flexural modulus promoted to some extent was obtained.更多还原
