Multi-layer moulding, containing a body part and a surface layer which at least partly covers the body part, which body part contains a cross-linked elastomer composition and which surface layer contains a thermoplastic elastomer, in which the surface layer of the multi-layer moulding, in a weather resistance test according to DIN 75202, in which the surface layer is continuously exposed for at most 100 hours to light from a xenon light source, which light source is provided with a borosilicate 'S' inner filter and a soda lime outer filter, at a relative humidity of 30%, with an intensity of 1.40 W/mat 420 nanometres on the surface of the moulding, a black standard temperature of 100&#xb0; C., in a space with a temperature of 66&#xb0; C., develops a colour deviation with a &#x394;E of at most 3.0, measured according to ASTM D 1925.

Multi-layer moulding

The subject invention relates to a thermoplastic elastomer composition that contains a dynamically vulcanized thermoplastic elastomer (a) on the basis of a thermoplastic polyolefin and an at least partly dynamically vulcanized rubber, a thermoplastic polyester block copolymer (b) and a compatibilizer (c). The thermoplastic polyolefin is preferably a propylene homo- or copolymer. The rubber is preferably an EPDM or EPM copolymer. The thermoplastic polyester block copolymer is preferably a polyether ester block copolymer. The thermoplastic elastomer composition according to the invention for instance contains 20-80 parts (a), 80-20 parts (b), and 1-40 parts (c), the sum of the parts (a&plus;b&plus;c) being 100. The thermoplastic elastomer composition according to the invention also relates to molded articles that contains the thermoplastic elastomer composition.

Thermoplastic elastomer composition and molded articles made thereof

An elastic fiber of a mixture containing a copolyether ester or a copolyester ester and a chemically crosslinked rubber, which fiber has a permanent elongation after 100% stretching of at most 9% and an elongation at break of at least 450% and a process for producing an elastic fiber comprising the melt spinning of a mixture of a copolyether ester or a copolyester ester and a rubber to form a fiber, in which the rubber is completely or almost completely crosslinked at the moment the fiber is formed, and are disclosed.
