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 -羥基苯酮鈦[ （ hmbp ） _ 2ticl _ 2 ]的催化活性低於-二酮鈦類催化劑；雙核催化劑在催化活性方面與對應單核催化劑相差不多，但在聚合規律上表現出與單核催化劑不同的雙核協同作用，如聚合所需的催化劑濃度、助催化劑甲基
鋁氧
烷mao量降低，活性在80時出現極值，熔點提高等，而且雙核催化劑是單活性中心催化劑。
