Process for producing a shaped article

摘要: Process for producing a shaped article of polymer composition containing thermoplastic elastomer (A) chosen out the group copolyester elastomer, copolyamide and polyurethane comprising steps: 1) providing pre-form at temperature above melting composition, 2) shaping into shape article, 3) cooling down to obtain characterized in that, contains a (B) that has ratio η * ⁢ 1 / 2 > 5 η*1 is complex shear viscosity second measured 240° C rate 0.1 rad/s, η*2 100 both viscosities according ISO 6721-10:1999.
