catalyst concentration meaning in English
促进剂用量
Examples
- The copolymerizations of p - methylstyrene and styrene , styrene and ethylene were also investigated using some of these catalytic systems . the three kinds of catalysts showed their own polymerization principles . the changes of polymerization activity and polymer properties depended on the structure of complexes , different polymerization conditions such as the catalyst concentration , the molar ratio of al to ti , the polymerization temperature and reaction time
三类催化剂催化苯乙烯和p -甲基苯乙烯均聚时都有各自一定的聚合规律，不同的配体结构，聚合条件催化剂浓度、铝钛比、聚合温度和反应时间对聚合活性以及聚合物的性质有很大影响。 - The catalytic activity of ( hmbp ) 2ticl2was lower than - diketonate titanium catalysts . the catalytic activity of dinuclear - diketonate titanium catalysts was comparative to mononuclear ones . however , the dinuclear - diketonate titanium catalyst showed the synergism effect , for example , the lower catalyst concentration and the molar ratio of al to ti , the activity reached the maximum value at 80 , the melting temperature of polymer was enhanced
2 -羟基苯酮钛[ ( hmbp ) _ 2ticl _ 2 ]的催化活性低于-二酮钛类催化剂；双核催化剂在催化活性方面与对应单核催化剂相差不多，但在聚合规律上表现出与单核催化剂不同的双核协同作用，如聚合所需的催化剂浓度、助催化剂甲基铝氧烷mao量降低，活性在80时出现极值，熔点提高等，而且双核催化剂是单活性中心催化剂。
