Abstract:
PROBLEM TO BE SOLVED: To provide a thermoplastic polyester molding material having good flowability as well as good mechanical properties. SOLUTION: The thermoplastic molding material contains (A) 10 to 99.99 mass% of at least one thermoplastic polyester, (B) 0.01 to 50 mass% of a highly branched polyester or hyperbranched polyester of the type A x B y , wherein x represents at least 1.1 and y represents at least 2.1, and (C) 0 to 60 mass% of other additives, with the total sum by mass% of the components (A) to (C) being equal to 100%. According to the invention, the processing of the individual components is problem-free (without clumping or scorching) and possible within short cycle times, and in particular, the material can be used for thin-walled structural members.

Abstract:
The present invention relates to a method for producing fiber-reinforced composite materials, by saturating a plurality of continuous filaments or woven fabrics, optionally together with reinforcement materials, containing caprolactam and other starting materials for polyamide 6, or other starting materials for copolymers of the caprolactam, passing the materials through at temperatures between 70 and 100ºC, and anionically polymerizing them at temperatures between 100 and 190ºC, and optionally re-polymerizing them at temperatures between 90 and 170ºC.
Abstract:
A process for crosslinking polyamides by reacting a compound of the general formula R1R2C=CR3-X, in which R1, R2 and R3 are each independently hydrogen or an organic radical with a lactam A at a temperature of (-30) to 150°C and then with a lactam B, a catalyst and an activator at a temperature of 40 to 240°C.
Abstract:
The invention relates to polyester mixtures containing i) between 75 and 95 % by weight, in relation to the total weight of components i and ii, of at least one polyhydroxyalkanoate and ii) between 5 and 25 % by weight, in relation to the total weight of components i and ii, of a lactone or lactam. The invention also relates to a method for preventing the thermal degradation of polyhydroxyalkanoates by the addition of lactones and lactams.
Abstract:
The invention relates to a particle foam which contains 0.5 to 8 wt.-% of one or more corrosion inhibitors, selected from among amines, triazoles, carboxylic acid esters, carboxylic acid salts, nitrites, alcohols or mixtures thereof, to methods for producing said foam and to the use for packaging corrodible metal articles.
Abstract:
The invention relates to a method for obtaining water for domestic use by the condensation of mist on the webs of an open-cell aminoplast-based foam and/or to a method for obtaining water for domestic use by the evaporation of water containing salt or impurities from the cells of an open-cell aminoplast-based foam and by the condensation of the evaporated water. The open-cell foam is produced from a melamine/formaldehyde condensation product with a molar ratio of melamine to formaldehyde ranging between 1:1 and 1:5.
Abstract:
The invention relates to a liquid-impregnated foamed plastic part consisting of a) between 1 and 10 % by volume of an aminoplastic-based, open-pored foamed plastic and b) between 90 and 99 % by volume of a component that is liquid at 25°C, such as aromatic or aliphatic hydrocarbons, alcohols, ketones, water or aqueous dispersions, and to the uses of said part for transporting or metering liquids, for freeze-explosion purposes, for projectile energy absorption or as a latent heat accumulator.
