Abstract
The present invention pertains to a polyethylene polymer characterized by the following properties: A number average molecular weight Mn of at least 2.0*105 g/mol, a weight average molecular weight of at least 2.0*106 g/mol, a Mw/Mn ratio of above 6, and a strain hardening slope of below 0.10 N/mm at 135° C. It has been found that a polymer with these properties have be converted through solid state processing into films and fibers with good properties. A solid state processing process, films and fibers, and their use are also claimed.
