Abstract: The present invention relates to novel and improved polyamides composed of meta-xylylenediamine and having an amino end group content of less than 15 mmol/kg. Also found have been processes for preparing these polyamides composed of meta-xylylenediamine and adipic acid and having an amino end group content of less than 15 mmol/kg, which comprises reacting salt solutions of adipic acid and m-xylylenediamine at temperatures of from 80 to 300° C. and a pressure of from 1 to 20 bar with removal of water.

Abstract: The invention relates to a method for producing thermotropic (mono) films or composite films that contain at least one thermotropic layer that consists of a) 5 to 95 weight percent of a polymer as the component A, and b) 5 to 95 weight percent of a polymer as the component B that is different from A. A molecular mixture of components A and B has a cloud point below which the mixture is monophase and transparent and above which the mixture segregates into the components A and B. The components A and/or B may contain up to 15 mole percent of photoinitiator comonomers polymerized into the component. The layer contains optionally further components and optionally a support layer and/or a cover layer and optionally additional intermediate layers. The inventive method comprises the following steps: i) producing an intimate mixture that contains 10 to 98 weight percent of a mixture of components A, B and optionally further components and 2 to 90 weight percent of a solvent in which the components A and B are soluble, ii) removing the solvent, whereby an intimate polymer mixture from the components A and B and optionally further components is produced, iii) melting the intimate polymer mixture from step (ii) during or after the removal of the solvent, iv) optionally adding further components at a random point in time, v) shaping the mixture from components A, B and optionally further components to give a thermotropic (mono) film or, together with the support film and/or the cover layer and optionally the additional intermediate layers, to give a thermotropic composite film, and vi) optionally cross-linking said thermotropic film or said thermotropic composite film by UV radiation.

Abstract: Substituted sulfonylureas of the formula I I where R1 is hydrogen, C1-C4-alkyl, C3-C4-alkenyl or alkynyl, C1-C4-haloalkyl, C3-C6-alkoxyalkyl, C4-C6-haloalkoxyalkyl or C5-C6-cycloalkyl, R2 is hydrogen, methyl or ethyl, R3 is hydrogen, halogen, methyl or methoxy, R4 is hydrogen, methyl or methoxy, X is N or C-H, and Hal is fluorine, chlorine or bromine, and alkali metal or alkaline earth metal salts thereof, with the proviso that R1 is not methyl when Hal is chlorine and X is N, a process for the manufacture of sulfonylureas of the formula I and their use as herbicides.
