Publication number: 20230037314Abstract: A moulding composition contains a) 75 wt. % to 98.5 wt. % of a polyether block amide, based on a total weight of the moulding composition. The polyether block amide contains a subunit 1, composed of at least one lactam or ?,?-aminocarboxylic acid having 6 to 14 carbon atoms, and a subunit 2, composed of at least one amino- or hydroxy-terminated polyether having at least two carbon atoms per ether oxygen and at least two primary amino or at least two hydroxy groups at the chain ends. The moulding composition also contains b) 1.5 wt. % to 25 wt. % of at least one polyalkenamer, based on a total weight of the moulding composition. The at least one polyalkenamer contains at least one cycloalkene having 5 to 12 carbon atoms. A moulded article can be produced from the moulding composition, which can be a moulding, a film, a bristle, a fibre or a foam.Type: ApplicationFiled: December 19, 2019Publication date: February 9, 2023Applicant: Evonik Operations GmbHInventors: Chenyu Ye, Kathrin Salwiczek, Urs Welz-Biermann, Klaus Hülsmann, Peter Hannen, He Zhang

Publication number: 20220372256Abstract: A method for producing a rubber-plastic composite, including the steps of (a) shaping an unvulcanized elastomer, (b) partially vulcanizing the shaped elastomer at a temperature of at least 140° C. up to a degree of vulcanization in the range from 10% to 40%, (c) cooling the partially vulcanized elastomer to a temperature of less than 100° C. within less than 20 minutes, (d) overmolding the partially vulcanized elastomer with a plastic, and (e) heat treating the partially vulcanized elastomer overmolded with a plastic at a temperature in the range from 100° C. to 170° C. for a duration of from 5 minutes to 5 hours to complete the vulcanization and form a rubber-plastic composite. The method further relates to a rubber-plastic composite obtainable by the method according to the invention and also to a shoe comprising the rubber-plastic composite obtainable by the method according to the invention.Type: ApplicationFiled: September 1, 2020Publication date: November 24, 2022Applicant: Continental Reifen Deutschland GmbHInventors: Konstantin Efimov, Anna-Lena Dreier, Klaus Hülsmann, Andreas Pawlik, Marco Kormann, Maximilian Drexler

Publication number: 20220195145Abstract: A polyamide composition contains a) 88.5-98 wt. % of at least one aliphatic polyamide, wherein at least one monomer unit has 10 to 14 carbon atoms, and wherein the aliphatic polyamide is semi-crystalline; and b) 2-11.5 wt. % of an S glass fiber. The weight percentages of a) and b) are based on a total weight of the polyamide composition. The polyamide composition contains neither a polyolefinic impact modifier nor a core-shell modifier. A moulding material containing the polyamide composition is useful, and a moulded article can be produced from the moulding material. A shoe outsole containing the polyamide composition is also useful.Type: ApplicationFiled: May 9, 2020Publication date: June 23, 2022Applicants: Evonik Operations GmbH, Evonik Specialty Chemicals (Shanghai) Co., Ltd.Inventors: Kathrin Salwiczek, Chenyu Ye, Urs Welz-Biermann, Klaus Hülsmann, Fei Teng, Zhisheng Wang, Juan Guo
