Abstract
The present invention relates to catalyst field, in particular it relates to a kind of method that cycloolefin ring-opening polymerisation is carried out for the catalyst system and catalyzing of cycloolefin ring-opening polymerisation and using the catalyst system and catalyzing.The catalyst system and catalyzing has included the component A of major catalyst effect and has played the pre- ageing mixture of co-catalyst, and the pre- ageing mixture is by the way that component B and component C mixture ageing are obtained；Wherein component A is MoCl5And/or WCl6；Component B is that chemical formula is AlR3And/or AlHR2Organo-aluminum compound, wherein R be C1 C6 alkyl；Component C is chlorohydrocarbon.The property of the catalyst system and catalyzing of the present invention is more stablized, and cost is lower, and preferable conversion ratio can be realized during for cycloolefin ring-opening polymerization and is operated safer.
Description
Technical field
The present invention relates to catalyst field, in particular it relates to a kind of urging for cycloolefin ring-opening polymerisation
Change system and the method that cycloolefin ring-opening polymerisation is carried out using the catalyst system and catalyzing.
Background technology
Ring-opening metathesis polymerization is the important chemical reaction of a class, can take this to synthesize various new high score
Sub- material.In association area research, the selection of catalyst and prepare the most key.Open loop can be realized
The catalyst of polymerization has a lot, is broadly divided into four classes：(1) metal carbene catalyst.Also known as alkylene
Base class catalyst, the main metallic element of this kind of catalyst mainly has titanium, tungsten, molybdenum, the class of ruthenium four.Wherein
Active highest is molybdenum class (Schrock catalyst) and ruthenium class (Grubbs catalyst).This kind of catalysis
Agent activity is high and stably, but synthesis step is more, and synthesis technique requires harsh therefore expensive.(2)
Metallocene catalyst.Metallocene catalysis system is main by metallocene (such as titanocenes) and RMgBr or gold
Belong to alkylates composition.Research of this kind of catalyst in terms of ring-opening metathesis polymerization is less, and catalyst
Activity is than above-mentioned metal carbene catalyst order of magnitude lower.(3) water-soluble catalyst.This kind of catalysis
Agent is mainly RuC13Hyrate.The catalyst can be catalyzed norborneol under the conditions of ethanol and water-soluble emulsion
Ene derivative occur open loop sigmatropic reaction, but this kind of catalyst generally activity it is relatively low, therefore study compared with
It is few.(4) Ziegler-natta catalyst.The catalyst is usually bi-component catalyst system and catalyzing, main catalytic
Agent is the compound of the elements such as W, Mo, Ru, Ti, such as WCl6、WOCl4、SnR2H etc.；Help and urge
Agent is the metallo-organic compounds, such as AlR such as Al, Mg3、AlR2Cl、Al2R3Cl3Deng (R is first
Base, ethyl or isobutyl group).The catalyst system and catalyzing biggest advantage being made up of these components is that cost is low
It is honest and clean, it is adapted to heavy industrialization batch production.
In Ziegler-natta catalyst, the most commonly used major catalyst is MoCl5And WCl6, but only
Using only major catalyst, cycloolefin ring-opening polymerisation is without activity, because must be added to co-catalyst.When
When adding alkyl aluminum class material, such as in MoCl5Add AlEt3Binary catalyst is constituted, for bicyclic penta
During diene polymerization, the smell of gained dicyclopentadiene is very big, illustrates there are a large amount of unreacted monomers, shows
Catalyst activity is very low.In order to solve the problem, AlCl is added again3To improve activity (referring to perhaps refined, multitude
Huaming, once sub- child, waited .MoC15-AlCl3-AlEt3The polymerisation research for being catalyzed dicyclopentadiene is closed
Resin and plastics, 1997,14 (4):22-24).When using chlorination alkyl aluminum class for co-catalyst, lead to
Higher activity, such as WCl often can be obtained6/AlEt2Cl systems are (referring to Liu Pengsheng, Li Huaming bicyclic penta
Diene reaction injection molding plastics industries, 1993, (1):31-38) and MoCl5/AlEt2Cl systems are (referring to Liu
Tiger, Yao great Hu, horse Panpan waits the open loop of molybdenum bases to shift catalyst dicyclopentadiene polymerization studies thermosettings
Resin, 2012,27 (5):36-39).
However, chlorination alkyl aluminum (such as AlEt2Cl be) a class property very active material, easily with
Water is reacted and failed, even minor amount of water present in air, chlorination alkyl aluminum can be reacted,
White cigarette is produced, big calorimetric is released, triggers peril, therefore, it is necessary to tight for industrial production
Lattice closed-loop operation.Meanwhile, chlorination alkyl aluminum is also the expensive material of a class, for industrial production
For, have the shortcomings that catalyst cost is higher.
The content of the invention
The purpose of the present invention is to overcome in existing cycloolefin ring-opening polymerization method to make using chlorination alkyl aluminum
