摘要： a film formed from a copolyme of ethylene and at least one mono-.alpha.-olefine has a combination of impact strength and stiffness which is such that the function ##EQU1## IS AT LEAST 750. The function is preferably at least 1000 and may be several thousands. The film may also have a high tear strength and good tensile strength.The copolymer from which the film is formed is preferably one in which the comonomer contains at least 5 carbon atoms; the comonomer conveniently contains not more than 12 carbon atoms. The comonomer content of the polymer is typically in the range from 6.5 up to 30%, by weight.The film can be produced by a tubular film technique using a temperature of 170.degree.-300.degree. C, a circumferential expansion of 1.2 to 10.0 times and a draw down of 2.5 to 50 times. The production of the polymeric film can include extruding the ethylene copolymer through an annular dye, maintaining the dye temperature in the range from 170.degree.-300.degree. C, blowing the exudate to give a circumferential expansion of from 1.2 up to 10.0 times and drawing the exudate to give a draw down of from 2.5 up to 50 times.

摘要： a copolymer of ethylene with at least one other mono-.alpha.-olefine is prepared and is characterized as having a density in the range 918 to 940 Kg/m.sup.3, an apparent viscosity (A) at 200.degree. C and a shear rate of 100 sec.sup.1 of 0.5 .times. 10.sup.3 to 3.0 .times. 10.sup.3 Nsm.sup.2 and a viscosity at 200.degree. C and a stress of 10.sup.3 N/m.sup.2 of 2 Ae.sup.(1.6A 10 ) to 10,000 A.The copolymer from which the film is formed is preferably one in which the comonomer contains at least 5 carbon atoms; the comonomer may contain up to 12 carbon atoms. Hexene-1 is the preferred comonomer and can be present in the copolymer in an amount of 6.5 to 16.5%, by weight.The copolymers are readily processed and can be formed into films which combine good stiffness and good impact properties.The copolymers are conveniently prepared using supported transition metal benzyl compounds followed by a total work-up of the polymerization mixture. In particular, a process for forming the copolymers includes copolymerizing ethylene and the comonomer in the presence of a transition metal olefine polymerization catalyst and separating a polymeric product having an annealed characteristic set forth above.

摘要： a process for the separation of diluent from an ethylene polymerization reaction mixture wherein ethylene is copolymerized using as a catalyst an organo-metallic compound supported on an inorganic material. Subsequent to reaction, there is added to the reaction mixture a wetting agent and the diluent is then removed from the reaction mixture by steam distillation to give a product having significant solubility in the diluent.A wide variety of wetting agents may be used, which may be either water-soluble or water-insoluble. However, water soluble wetting agents are much preferred, so that most or at least some of the wetting agent remains in the aqueous phase at the end of the steam distillation step. The wetting agent may also possess hydrocarbon solubility; but this does not appear to be of paramount importance. It should also be stable at the steam distillation temperature and should have low steam volatility. It is also convenient if the wetting agent is biodegradable to alleviate effluent disposal problems.Examples of wetting agents include water soluble salts of di(hydrocarbyl) sulphosuccinic acids; poly(ethylene oxides) terminated with branched fluorocarbon groups, adducts of linear alcohols with ethylene oxide, and block copolymers of ethylene oxide and propylene oxide.In general concentrations of wetting agent in the range 0.005 to 0.10% weight/volume, calculated on diluent, are suitable. Preferred concentrations are generally in the range 0.01 to 0.06% weight/volume.

摘要： Fibrils of thermoplastic polymer, particularly crystalline thermoplastic polymers such as polyethylene and polypropylene, are prepared by forcing a dispersion of heat softened polymer particles in a liquid medium through a pair of opposed co-axial orifices. The liquid medium is preferably aqueous and is pressurized to prevent boiling. The resulting fibrils have some degree of molecular orientation, and may be useful in the production of reinforced paper.
