    Abstract: A block copolymer contains at least a block (P1) and a block (P2). The block (P1) is obtained or obtainable by reaction of a triblock copolymer having the structure A-B-A′, where block B is selected from polyethers or polyesters and blocks A and A′ are identical or different, and at least one polymer (PM) selected from polyesters and polyethers. The block (P2) is selected from polyamides and polyesters. A process can be used for producing the inventive block copolymer, a shaped article can be made containing the inventive block copolymer, and the inventive block copolymer can be used for producing a shaped article.

    Abstract: Molded articles contain a foam composed of a thermoplastic elastotner (TPE-1). The foam has a storage modulus (G modulus) at 25° C. and 1 Hz within the range from 0.01 to 0.5 MPa, a molding density within the range from 20 to 400 kg/m3, and a comfort factor of greater than 4. A process produces molded articles of this kind, and the molded article can be used for producing floors, mattresses, seating furniture, bicycle saddles, car seats, motorcycle seats, components of a shoe, shoe inserts, packaging, shock absorbers, protectors, fall protection mats, elastic insulating material, or sealing material.

    Abstract: Provided herein is a process for producing a polyamide (P) by reaction of a mixture (M) including at least one lactam (component (A)), at least one catalyst (component (B)), at least one activator (component (C)), and at least one oxazolidine derivative (component (D)). Further provided herein is the mixture (M) and the use of an oxazolidine derivative for increasing the crystallization rate of a polyamide (P). Also provided herein is the use of an oxazolidine derivative in a polyamide (P) for producing a molded article from the polyamide (P) for reducing the demolding time of the molded article and the use of an oxazolidine derivative for removing water from a reaction mixture (RM).

    Abstract: A process for the production of a polyamide is disclosed. The process for production of a polyamide (P) comprises mixing a first mixture (M1), which comprises at least one lactam and at least one catalyst, with a second mixture (M2), which comprises at least one lactam, at least one activator and at least one amine, to give a polymerizable mixture (pM) and then polymerization of the polymerizable mixture (pM) to give the polyamide (P). A polyamide (P) obtainable by the process of the invention is also disclosed, as well as moldings made of the polyamide (P).
