Abstract:
Die vorliegende Erfindung betrifft silylierte Melamin-Formaldehyd-Harze, Verfahren zu deren Herstellung, deren Verwendung und solche enthaltende Beschichtungsmassen.
Abstract:
The invention relates to a method for producing polyesterols from at least one base polyesterol and at least one additional reagent. According to said method, (a) the base polyesterol(s) and the additional reagent(s) are mixed and (b) the mixture produced in (a) passes through a reactor containing at least one packing section with an immobilised enzyme that is situated on a support, allowing the base polyesterol(s) and the additional reagent(s) to be converted into the polyesterol.
Abstract:
The invention relates to thermoplastic molding materials containing: A) 10 to 98 % by weight of at least one thermoplastic polymer; B) 0.01 to 50 % by weight of; B1) at least one highly branched or hyperbranched polycarbonate with an OH number ranging from 1 to 600 mg KOH/g of polycarbonate (in accordance with DIN 53240, part 2) or; B2) at least one highly branched or hyperbranched polyester of type AxBy with x being at least 1.1 and y being at least 2.1 or mixtures consisting of B1) and B2); C) 1 to 30 % by weight of a flameproofing agent combination consisting, with regard to 100 % by weight of C), of; C1) 20 to 99 % by weight of a halogen-containing flameproofing agent; C2) 1 to 80 % by weight of an antimony oxide, and; D) 0 to 60 % by weight of additional additives, the sum of the weight percentages of constituents A) to D) totaling 100 %.
Abstract:
The invention relates to a method for producing highly branched or hyperbranched polyamides. The inventive method is characterized by reacting a first monomer A 2 having at least two functional groups A, with a second monomer B 3 having at least three functional groups B, whereby 1) the functional groups A and B react with each other, and 2) one of the monomers A and B is an amine and the other of the two monomers A and B is a carboxylic acid, and 3) the molar ration of A 2 : B 3 ranges from 1.1:1 to 20:1.
