摘要： Method of determining the composition of polymer mixtures comprising defined polymer components of differing mean molar masses Mn, which comprises the steps (a) recording of at least one 1H-NMR relaxation curve of the polymer mixture and (b) calculating the proportions of the polymer components by matching the measured relaxation curve with the relaxation curves of the individual polymer components. In this way, the composition of polymer mixtures can be determined quickly and simply. Furthermore, process integration for regulating the polymerization is possible.

摘要： The invention relates to a partly crystalline propylene polymerisate composition which is produced by polymerisation of propylene, ethylene and/or C4-C18 alk-1-enes, whereby at least 50 mol. % of the contained monomer units are derived from propylene and at least 20 wt. % of the propylene polymerisate composition arises from polymerisation by means of metallocene catalysts, with a melting temperature TM in the range from 65 °C to 170 °C. The partly crystalline propylene polymerisate composition may be broken down into from 65 to 85 wt. % of a main component A, from 10 to 35 wt. % of a further component B and from 0 to 25 wt. % of a further component C, whereby the fraction for components A, B and C may be determined by a TREF (Temperature Rising Elution Fractionation).

摘要： The invention relates to a method for drying and degassing polyolefins. The polymerisation matter leaving a polymerisation reactor is contacted with a degassing medium and relaxed at the same time. According to the invention, the monomer to be polymerised is used as the degassing medium. Said monomer flows through a relaxation container, especially in a cycle process, and is preferably enriched with ethylene or other low-boiling olefins in an amount ranging from 0 to 100 mol % in relation to the entire amount of the cycle gas. Polymerisation is carried out in the relaxation container in an amount of up to 10 % in relation to the entire polymerisation conversion.
