Application No. 08/120,105
APPENDIX
17. A process for the preparation of a polyolefin molding
composition comprising at least two polyolefinic components,
wherein the composition is characterized by a broad,
bimodal, or multimodal melting range in a DSC spectrum
determined with a heating/cooling rate of 20°C/min wherein
the peak in the melting range has a maximum and can be
bimodal or multimodal and the maximum of the peak in the
melting range is between 120 and 165°C, the half-intensity
width of the melting peak is broader than 10°C and the width
determined at quarter peak height is greater that 15°C,
wherein such process comprises the direct polymerization of
propylene or copolymerization of propylene with olefins of
the formula RaCH=CHRb, in which Ra and Rb are identical or
different and are a hydrogen atom or an alkyl radical having
2 to 14 carbon atoms wherein the polymerized ethylene
content of the resulting polyolefin composition is from 0 to
2.5% by weight,
to at least two polyolefins of different melting points,
wherein the melting points of the polyolefins must differ by
at least 5°C, and wherein the polymerization is carried out
at a temperature of from -60 to 200°C, and a pressure of
-1-
