Abstract: Rheological properties determine the suitability for biaxial orientation. The suitability of a partially crystalline polymers, especially a polypropylene polymer, for the preparation of biaxially oriented foils and films can be decided by determination of its rheological properties. The method involves determination of the viscosity change with temperature in the region of the melting point, definition of a characteristic quantity in such a way that its value is inversely related to the viscosity change with temperature, determination of the extent of strain hardening on partial melting of the polymer, for which a characteristic quantity is so defined that its value is the greater the more marked the strain hardening. Both characteristic quantities when multiplied together are coupled to an end characteristic quantity, so that the suitability of the partially crystalline polymer is the better the larger the value of the end characteristic quantity.

Abstract: A process for preparing a supported transition metal catalyst comprising a particulate organic or inorganic support material, a transition metal complex and a compound capable of forming metallocenium ions comprises the following process steps:a) contacting a solution of a compound capable of forming metallocenium ions with a second solvent in which this compound is only sparingly soluble, in the presence of the support material,b) removing at least part of the solvent from the support material andc) contacting a solution of a mixture of a compound capable of forming metallocenium ions and a transition metal complex with a second solvent in which this mixture is only sparingly soluble, in the presence of the support material obtained as described in a) and b).
