Abstract: Preparation of polyoxymethylene (I) comprises polymerizing their monomers in the presence of cationically active initiators and optional regulators, subsequently deactivating and separating (I), where the polymerization is carried out in tubular reactor (A) (with static mixing element) comprising mixing-, polymerizing- and deactivating zones and the diameter of (A) in the mixing zone is less than 90% of the diameter in the polymerizing zone. An independent claim is also included for polyoxymethylene homo-/co-polymer obtained by the above method, where the quotient of d 50/d 100-value (related to M w) is 2.25-5.5.

Abstract: In a process for distillatively removing ammonia and water from mixtures obtained in the preparation of polyamides which comprise a lactam and/or diamines, and, if appropriate, an aminonitrile and/or dinitrile, and also a cyclopentanone impurity in two stages: 1) the mixture is distilled at from 11 to 35 bar to give, as the top product T1, water, ammonia and cyclopentanone, and, as the bottoms B1, water, the lactam and/or diamines, and, if appropriate, the aminonitrile and/or dinitrile, and 2) T1 is distilled at from 11 to 35 bar to give, as the top product T2, ammonia and cyclopentanone, and, as the bottoms B2, water.

Abstract: A method for making aqueous copolymer dispersions by radical emulsion polymerisation using the monomer feed method, in which the monomers comprise 70-99.5 wt% alpha ,beta -mono-unsaturated monomers (A), 0.5-30 wt% polyfunctional comonomers (B) and optionally up to 5 wt% alpha ,beta -mono-unsaturated 3-6C mono- or di-carboxylic acids and/or amides (C), and at least 60 wt% of the total amount of (B) is added after at least 60 wt% of the total amount of all monomers has been added. A method for the production of aqueous copolymer dispersions (I) by radical-initiated emulsion polymerisation of unsaturated monomers in presence of dispersants and radical initiators using the monomer-feed method, in which the monomers used comprise 70-99.5 wt% alpha ,beta -mono-unsaturated compounds (monomers A), 0.5-30 wt% compounds with at least two copolymerisable unsaturated groups (B) and optionally up to 5 wt% alpha ,beta -mono-unsaturated 3-6C mono- or di-carboxylic acids and/or amides, and at least 60 wt% of the total amount of (B) is added under polymerisation conditions after at least 60 wt% of the total amount of all monomers has been added. Independent claims are included for (1) aqueous copolymer dispersions obtained by this method (2) copolymer powders obtained by drying these dispersions .

Abstract: The invention relates to a porous metal-organic framework material for taking up at least one substance, the framework material comprising at least one at least bidentate organic compound bound by coordination to at least one metal ion, and the framework material having at least in part pores which comprise a polymer which is suitable to adsorb the at least one substance. In addition, the invention relates to a method for producing the framework material, a method for taking up at least one substance by the framework material and also to the use of the framework material, in particular for the storage, separation, controlled release or chemical reaction of a substance taken up.
