摘要： The present invention relates to a process for the continuous polymerisation of isobutene while maintaining at a constant desired value a property P (viscosity or average molecular mass) of the polymer produced. The polymerisation is conducted in a reactor comprising a boiling liquid reaction phase which contains the monomer and the polymer being formed, in equilibrium with a gas phase on top of the said liquid phase, by continuous introduction into the reactor of a catalyst and of a C4 hydrocarbon feed mixture comprising the monomer, and by continuous withdrawal from the reactor of the liquid reaction phase, which is subsequently subjected continuously to at least one purification step which is intended to isolate the polyisobutene produced. The process comprises the determination of a target value V of the partial pressure piC4 of the isobutene in the gas phase of the reactor corresponding to the property P, by virtue of an empirical relationship established beforehand between the property P of the polyisobutene produced and piC4. During the polymerization, piC4 is measured and held constant at around the target value V by acting on the flow rate Qc of the catalyst introduced into the reactor and/or on the flow rate Qh of the C4 hydrocarbon feed mixture.

The inventive method is characterized in that the polymerization is carried out in the presence of an initiator system comprising: i) a Lewis acid selected among covalent metal chlorides and metalloid chlorides, and; ii) at least one organic compound (I) having at least one functional group FG that, together with the Lewis acid, forms a carbocation or a cationogenic complex under polymerization conditions, whereby FG is selected among acyloxy, alkoxy or halogen, which are bound to a secondary or tertiary C atom, to an allylic C atom or to a benzylic C atom. Said polymerization is carried out in a solvent that is inert to the Lewis acid, whereby the Lewis acid is used in molar deficiency with regard to the functional groups FG.

摘要： A compound containing a primary hydroxyl group and an unsaturated bond is caused to act on a halogen-terminated hydrocarbon polymer obtained by cationic polymerization to obtain a saturated hydrocarbon polymer having a hydroxyl group at each end. Compounds obtained by quantitatively incorporating hydroxyl groups at the ends of saturated hydrocarbon polymers obtained by cationic living polymerization are useful as materials for highly weatherable urethanes. In a conventional method known as a technique for obtaining such hydroxyl-terminated compounds, the polymer ends after completion of polymerization are converted to olefinic ends and then subjected to hydroboration. However, this method needs a multistage reaction and requires much labor. It has become possible to obtain a hydroxyl-terminated saturated hydrocarbon polymer directly, i.e., without via an intermediate therefor, by reacting a compound containing a primary hydroxyl group and an unsaturated bond with a halogen-terminated hydrocarbon polymer obtained by cationic polymerization.

摘要： A novel liquid phase polymerization process for preparing a polyolefin product having preselected properties is disclosed. The process includes the steps of providing a liquid feedstock which contains an olefinic component and a catalyst composition consisting of a stable complex of BF3 and a complexing agent therefor. The feedstock may comprise any one or more of a number of olefins including branched olefins such as isobutylene, C3 to C15 linear alpha olefins and C4 to C15 reactive non-alphaolefins. The feedstock and the catalyst composition are introduced into a residual reaction mixture recirculating in a loop reactor reaction zone provided in the tube side of a shell and tube heat exchanger at a recirculation rate sufficient to cause intimate intermixing of the residual reaction mixture, the added feedstock and the added catalyst composition. The heat of the polymerization reaction is removed from the recirculating intimately intermixed reaction admixture at a rate calculated to provide a substantially constant reaction temperature therein while the same is recirculating in said reaction zone. The conditions in the reactor are appropriate for causing olefinic components introduced in said feedstock to undergo polymerization to form the desired polyolefin product in the presence of the catalyst composition. A product stream containing the desired polyolefin product is withdrawn from the reaction zone. The introduction of the feedstock into the reaction zone and the withdrawal of the product stream from the reaction zone are controlled such that the residence time of the olefinic components undergoing polymerization in the reaction zone is appropiate for production of the desired polyolefin product.
