Abstract
Monomodal copolymers of ethylene and molding compositions comprising such copolymers, wherein the copolymers have a density determined according to DIN EN ISO 1183-1, variant A in the range from 0.938 to 0.944 g/cm, a melt index MFRdetermined according to ISO 1133 at 190° C. under a load of 21.6 kg in the range from 12 to 17 g/10 min, a weight average molar mass Min the range from 140 000 g/mol to 330 000 g/mol, a polydispersity M/Min the range from 9 to 17, and a content of comonomer side chains per 1000 carbon atoms Cequal to or above a value defined via equation (I) C=128.7−134.62×d', wherein d′ is the numerical value of the density of the copolymer in g/cm, the use of the copolymers for producing injection-molded articles, as well as injection-molded articles comprising the copolymers, and process for the preparation of such monomodal copolymers.
