查询词典 peroxide

After the oxidative polymerization of DMP,styrene was in-situ polymerized under the initiation of dibenzoyl peroxide and dicumyl peroxide,finally thermodynamically compatible PPO/PS alloy was prepared.When styrene content was 50 wt%,for the synthesized PPO/PS alloy the yield and the weight-average molecular weight were determined to be 95%and 1.7×10~5 for PPO,93%and 2.0×10~5 for PS,respectively.The influence of the concentration of DMP and catalyst,molar ratio of N/Cu, oxygen partial pressure,NaOH concentration and temperature on the initial polymerization rate(R_0) of DMP was studied.It was found that the initial polymerization rate of DMP increased with the concentration of DMP and catalyst. The initial polymerization rate increased with the molar ratio of N/Cu at first and then decreased.
