Abstract: The invention concerns tetrahydrofuran/but-2-ine-1,4-diol copolymers containing C-C triple bonds, the copolymers having a mean molecular weight Mn of 500 to 3,500 Daltons and containing 0.5 to 3 moles of triple bonds per mole of copolymer, as well as blends of these copolymers with polytetrahydrofuran having a mean molecular weight Mn of 500 to 3,500 Daltons. The invention also concerns a method of producing such copolymers or blends and their use.

Abstract: 3-Arylacrylic acids and their derivatives I in which Ar represents an aryl radical which can additionally have substituents which do not react with ketene and which are stable to acids and bases under the conditions of the reaction described below, and R denotes hydrogen, alkali metal, alkaline earth metal, ammonium or a C1- to C20-alkyl group, are prepared by reacting, in a first reaction step, a dialkyl acetal of an aromatic aldehyde II in which R represents C1- to C4-alkyl, with ketene CH2=C=O in the presence of catalytic amounts of a protonic acid or a Lewis acid to give a 3-arylpropionic acid derivative III and reacting this intermediate III, in a second reaction step, in the presence of acid or base and, additionally in the case where R denotes a C1- to C20-alkyl group, with a C1- to C20-alkanol to give the end product I.

Abstract: A method is disclosed of producing polytetrahydrofurane or polytetrahydrofurane monoesters of C1-C10 monocarboxylic acids by polymerisation of tetrahydrofurane on a heterogenous catalyst in the presence of one of the following telogens: water, 1.4-butane diol, polytetrahydrofurane with a molecular weight of 200-700 Da, a C1-C10 monocarboxylic acid, or mixtures of these telogens. The catalyst used is a carrier catalyst which contains a catalytically active quantity of an oxygen-containing tungsten or molybdenum compound or mixtures of such compounds on an oxide carrier material and has undergone calcination at temperatures of 500-1000 DEG C after the precursors of the oxygen-containing molybdenum and/or tungsten compounds have been deposited on the carrier material precursor.
