Description
Technical field
The present invention relates to catalyst fields, and in particular, to a kind of catalyst system for cycloolefin ring-opening polymerisation and
The method for carrying out cycloolefin ring-opening polymerisation using the catalyst system.
Background technique
Ring-opening metathesis polymerization is a kind of important chemical reaction, can take this to synthesize various new high molecular material.In
In related fields research, the selection of catalyst and prepare the most key.The catalyst for being able to achieve ring-opening polymerisation has very much, substantially may be used
It is 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 have titanium,
Tungsten, molybdenum, four class of ruthenium.Wherein it is active it is highest be molybdenum class (Schrock catalyst) and ruthenium class (Grubbs catalyst).This kind of catalysis
Agent activity is high and stablizes, but synthesis step is more, and synthesis technology requires harsh therefore expensive.(2) metallocene catalyst.Cyclopentadienyl
Metal catalyst system is mainly made of metallocene (such as titanocenes) and Grignard Reagent or metal alkyls.This kind of catalyst is being opened
Research in terms of ring metathesis polymerization is less, and catalyst activity an order of magnitude lower than above-mentioned metal carbene catalyst.(3) water-soluble
Property catalyst.This kind of catalyst is mainly RuC13Hyrate.The catalyst can be catalyzed drop ice under the conditions of ethyl alcohol and water-soluble emulsion
Open loop sigmatropic reaction occurs for piece ene derivative, but this kind of catalyst usually activity is lower, therefore studies less.(4) Ziegler-is received
Type catalysts.The catalyst is usually bi-component catalyst system, the compound of the elements such as major catalyst W, Mo, Ru, Ti, such as
WCl6、WOCl4、SnR2H etc.；Co-catalyst is the metallo-organic compounds, such as AlR such as Al, Mg3、AlR2Cl、Al2R3Cl3Deng (R is
Methyl, ethyl or isobutyl group).The catalyst system biggest advantage being grouped as by these groups is low in cost, is suitble to extensive
Industrialized mass production.
In Ziegler-natta catalyst, the most commonly used major catalyst is MoCl5And WCl6, but main catalytic is only used only
Agent, cycloolefin ring-opening polymerisation is without activity, because must be added to co-catalyst.When alkyl aluminum substance is added, such as in MoCl5
AlEt is added3Binary catalyst is formed, when for dicyclopentadiene polymerization, the smell of gained dicyclopentadiene is very big, and explanation has
A large amount of unreacted monomers show that catalyst activity is very low.In order to solve this problem, and AlCl is added3To improve activity (referring to perhaps
Refined, Li Huaming, once sub- child, waited .MoC15-AlCl3-AlEt3It is catalyzed polymerization reaction research synthetic resin and the modeling of dicyclopentadiene
Material, 1997,14 (4): 22-24).When using chlorination alkyl aluminum class for co-catalyst, higher activity usually can be obtained, such as
WCl6/AlEt2Cl system (referring to Liu Pengsheng, Li Huaming dicyclopentadiene reaction injection molding plastics industry, 1993, (1):
31-38) and MoCl5/AlEt2Cl system (referring to Liu Hu, Yao great Hu, Ma Panpan, waits molybdenum base open loop displacement catalyst bicyclic
Pentadiene polymerization studies thermosetting resin, 2012,27 (5): 36-39).
However, chlorination alkyl aluminum (such as AlEt2Cl it is) the very active substance of a kind of property, easily reacts and lose with water
Effect, even minor amount of water present in air, chlorination alkyl aluminum can be reacted with it, and generate white cigarette, release big calorimetric, cause danger
Dangerous accident, therefore for industrial production, need stringent closed-loop operation.Meanwhile chlorination alkyl aluminum is also that a kind of price is more expensive
Substance, for industrial production, the shortcomings that there is catalyst higher costs.
Summary of the invention
The purpose of the present invention is overcome in existing cycloolefin ring-opening polymerization method to use chlorination alkyl aluminum as WCl6With/
Or MoCl5Co-catalyst when it is existing it is vulnerable, have the shortcomings that security risk, operation stringent and higher cost, provide one
Catalyst system of the kind for cycloolefin ring-opening polymerisation and the method using catalyst system progress cycloolefin ring-opening polymerisation.This hair
The property of bright catalyst system is more stable, and cost is lower, preferably turns for may be implemented when cycloolefin ring-opening polymerization
Rate and operate it is safer.
The present invention provides a kind of catalyst system, which has included the component A of major catalyst effect and has risen and help and urge
