Abstract:
The invention relates to ethylene terpolymers containing the following as comonomers incorporated by polymerisation: (a) ethylene, (b) at least one cyclic amide containing at least one ethylenically unsaturated group, and (c) at least one carboxylic acid that is ethylenically unsaturated at least once or at least one ester of a carboxylic acid that is ethylenically unsaturated at least once.

Abstract:
A crosslinkable copolyimide consisting mainly of repeating units derived from dianhydrides of given formula and containing primary amine groups, where these are in the ortho, meta, or para positions to the ether function is new. A crosslinkable copolyimide consisting mainly of repeating units derived from dianhydides of formula:(A), diamines of formula (I), diamines of formula (II): where the amino groups are in the ortho, meta, or para position, and 1 or 2 aromatic nucleus H atoms can be substituted by 1-4X alkyl, and diamines of formula (III):and containing primary amine groups, where these are in the ortho, meta, or para positions to the ether function. R1 = COOH or SO3H. Independent claims are included for: (1) membranes obtained from the crosslinked copolyimides; (2) chromatography columns containing the crosslinked copolyimides as the stationary phase; (3) a method of separating alcohols from mixtures with organic compounds of lower polarity than the alcohol, for separation of ammonia or amines from mixtures with organic compounds of lower polarity than ammonia, and for separation of water, ammonia, H2S, or organic compounds from mixtures with nitrogen or air, separation of olefins or dienes from mixtures with hydrocarbons of higher degree of saturation than the olefin or diene, e.g. separation of olefin/alkane using the membranes described or chromatography columns; (4) an olefin/alkane mixture enriched in olefin compared with the starting mixture by means of a membrane as described, and an alkane enriched stream separated, at a pressure on the membrane feed side higher than 6 bar.
Abstract:
Method for treating flexible substrates comprises coating at least one outer surface with a mixture containing at least one organic polymer and at least one inorganic or organic nano- or microparticular material, optionally fixing and treating the coated and optionally fixed flexible substrate with at least one acidic substance or at least one organic solvent. Independent claims are also included for: (1) the treated flexible substrate obtained by the method; (2) a method for preparing clothing articles, fabrics and sitting furniture by using the treated flexible substrate; and (3) clothing articles, fabrics and sitting furniture prepared under the use of the treated flexible substrate.
