| titleOfInvention | A kind of non-homogeneous polymerization catalyst and its preparing the application in homopolymer and copolymer |
| abstract | The present invention relates to a kind of non-homogeneous polymerization catalyst and its preparing the application in homopolymer and copolymer, non-homogeneous polymerization catalyst is mainly made of supported cocatalysts A and catalyst B, shown in the structure of catalyst B such as formula (I) or formula (II): In formula, R 1 ~R 5 It is each independently selected from hydrogen, alkyl, the substituent of alkyl, alkoxy, alkylthio group, halogen, nitro, aryl or aryl substituent, works as R 1 ~R 5 When middle adjacent group cyclization, the quantity of the ring structure of formation is less than 4, R 6 For alkyl or aryl, L is alkyl substituted phosphine or allyl.Non-homogeneous polymerization catalyst of the invention can be used for preparing homopolymer and copolymer, and activity is higher, have preferable tolerance to polar functional group, polymer molecular weight obtained is larger, and molecular weight distribution is relatively narrow, and form is controllable, without following process, glutinous kettle phenomenon can be effectively improved. |
