摘要： The invention provides a continuous process for catalytically polymerizing a monomer feed of ethylene and at least one comonomer which comprises introducing a catalyst including a bulky ancillary ligand transition metal compound and monomer feed in an upstream reaction zone for polymerization, introducing further catalyst in a downstream reaction zone for further polymerization, the peak temperature in the downstream reaction zone being at least 50 °C higher than in the upstream zone and being above 100 °C. The process economically produces polymer of good properties which is melt processable.

摘要： The process includes in a first aspect the steps of: a) continuously feeding olefinic monomer and a catalyst system of a metallocene component and a cocatalyst component to a reactor; b) continuously polymerising the monomer in the reactor under elevated pressure in a polymerisation zone; c) continuously removing a monomer/polymer mixture from the reactor; d) continuously separating monomer from molten polymer at a reduced pressure; and e) recycling separated monomer to the reactor characterised in that: f) a volatile catalyst system killer component and a non-volatile catalyst system killer component is added downstream of the polymerisation zone to act respectively to suppress polymerisation in the recycled monomer and the separated molten polymer. In a second aspect the process is basically the same but water is added as a volatile catalyst system killer component downstream of the polymerisation zone with preferably an amount of water being used which exceeds the level needed to kill the catalyst system components in recycled monomer and with a cocatalyst component being supplied to the reactor capable of reacting with the excess water.

摘要： The invention provides processes for producing a polyolefin at pressures substantially below conventional high pressure conditions in two-phase conditions below the cloud point. The invention may involve a continuous system with optional recycle. It can be used to produce ethylene copolymers at below 500 bars.

摘要： Procédés de production d'une polyoléfine à des pressions sensiblement inférieures aux pressions élevées traditionnelles, et dans des conditions à deux phases au-dessous du point de trouble d'écoulement. On peut employer un système continu avec recyclage éventuel, et l'utiliser pour produire des copolymères d'éthylène à des pressions inférieures à 500 bar.

摘要： Copolymers, and processes to make them, are provided which are derived from monomers comprising: a) one mono-olefin having a single Ziegler-Natta polymerizable bond; b) a second monomer having at least one Ziegler-Natta polymerizable bond; c) a third monomer having at least two Ziegler-Natta polymerizable bonds such monomer being: i) straight-chained and of less than six or at least seven carbon atoms; ii) other than straight chained; or iii) combinations thereof; such copolymer having: d) at least about one carbon-carbon unsaturated bond per number average molecule; e) viscous energy of activation (Ea) at least 1 kcal/mol greater than a copolymer having a linear backbone derived from same monomers, but excluding species having at least two Ziegler-Natta polymerizable bonds; f) crystallinity level of about 10 % to about 50 %; and g) Mz/Mw at least about 1.7. Such copolymers show enhanced melt processability and other attributes during end-product fabrication.

摘要： Dans un premier aspect le procédé comprend les étapes consistant: a) à verser de manière continue un monomère oléfinique ainsi qu'un système catalytique d'un composant d'alliage organométallique et d'un composé cocatalytique dans un réacteur; b) à polymériser de manière continue le monomère dans le réacteur sous haute pression dans une zone de polymérisation; c) à retirer de manière continue un mélange de monomère/polymère du réacteur; d) à séparer en continu un monomère d'un polymère fondu à une pression réduite; et e) à procéder au recyclage du monomère séparé dans le réacteur, caractérisé en ce que: f) un composant désactivateur de système catalytique volatil et un composant désactivateur de système catalytique non volatil sont ajoutés en aval de la zone de polymérisation afin de respectivement supprimer la polymérisation dans le monomère recyclé et le polymère fondu séparé. Dans un second aspect, le procédé est essentiellement le même mais on ajoute de l'eau utilisée comme composant désactivateur de système catalytique volatil en aval de la zone de polymérisation, la quantité d'eau utilisée dépassant de préférence le niveau nécessaire pour désactiver les composants du système catalytique dans le monomère recyclé, et un composant cocatalytique pouvant réagir avec l'eau excédentaire étant introduit dans le réacteur.
