Definitions
- EP-A-603 935 has described a molding composition based on polyethylene and having bimodal molar mass distribution and having suitability for production of moldings with good mechanical properties.
- low-molecular weight LMW, high-molecular weight HMW and ultra-high molecular weight UHMW are not meant to be absolute terms but in the context of the present invention, are only meant to be comparative terms positioning the at least three polymer fractions of the polymer of the present invention relative to each other, and in the order of increasing weight-average molecular weight.
- Weight distribution and weight average molecular weight can be determined according to ASTM D6474-1999 (2006), using as concentration detector a PolymerChar (Valencia, Paterna 46980, Spain) IR-4 infrared detector.
- the LMW, HMW and UHMW polymer fractions are different polymeric constituents.
- the viscosity number VN 1 measured on the polymer after the first polymerization stage is identical with the viscosity number VN A of the low-molecular-weight polyethylene A and according to the invention is in the range from 70 to 90 cm 3 /g.
- the inventive polyethylene molding composition can also comprise, alongside the polyethylene, further additives.
- additives are heat stabilizers, antioxidants, UV absorbers, light stabilizers, metal deactivators, compounds that destroy peroxide, and basic costabilizers, in amounts of from 0 to 10% by weight, preferably from 0 to 5% by weight, and also fillers, reinforcing agents, plasticizers, lubricants, emulsifiers, pigments, optical brighteners, flame retardants, antistatic agents, blowing agents, or a combination of these, in total amounts of from 0 to 50% by weight, based on the total weight of the mixture.
- the stress-cracking resistance of the inventive molding composition is determined by an internal test method and is stated in h. This laboratory method is described by M. Flei ⁇ ner in Kunststoffe 77 (1987), pp. 45 et seq., and corresponds to the ISO/CD 16770 standard which has now entered into force.
- the publication shows that there is a relationship between determination of slow crack growth in the creep test on specimens with peripheral notching and the brittle section of the long-term internal- and hydrostatic- pressure test to ISO 1167.
- time to failure is shortened because the crack-initiation time is shortened by the notch (1.6 mm/razor blade).
