摘要:
A fiber capable of forming a metal chelate and a process for producing the same are disclosed, wherein the fiber is characterized in that at least one metal chelate-forming compound selected from the group consisting of aminocarboxylic acid, aminocarboxylic acid, thiocarboxylic acid and phosphoric acid, which are reactive with a glycidyl group, is bonded to a molecule of a synthetic fiber through a crosslinkable compound having a reactive double bond and a glycidyl group in its molecule. The chelate-forming fiber is excellent in capturing harmful heavy metal ions and can be easily produced in a simple and safe way at a low cost.
摘要:
A description is given of novel stabilizer mixtures comprising at least one compound of the formula ##STR1## and at least one compound of the formula ##STR2## in which the variables are as defined in the claims. The novel stabilizer mixtures are suitable for stabilizing organic material, especially textile fibre materials, against damage by light, oxygen and heat.
摘要:
A process is described for the photochemical and thermal stabilisation of undyed and dyed polyester fibre materials, which comprises treating said materials with a compound of formula ##STR1## wherein R.sub.1 and R.sub.2 are each independently of the other C.sub.1 -C.sub.12 alkyl. Dyeings and prints of superior lightfastness and sublimation fastness on polyester and cellulose acetate are obtained by this process.
摘要:
Thermally stable textile lubricants obtained by reaction ofa) polyols withb) fatty acids containing 6 to 22 carbon atoms in the presence of 0.05 to 8% by weight, based on the sum of components a) and b), ofc) esters of thiocarboxylic acids corresponding to general formula (I) and/or (II):R.sup.1 --S--R.sup.2 --COOH (I)HOOC--R.sup.3 --S--R.sup.4 --COOH (II)in which R.sup.1, R.sup.2, R.sup.3 and R.sup.4 may be the same or different and represent an alkyl, cycloalkyl, aryl or alkaryl group containing 1 to 22 carbon atoms.
摘要:
The invention concerns a method for the chemical modification of a surface based on the reaction of photolytically generated reactive intermediates derived from azido heterocycles with said surface.
摘要:
A composition for increasing flame resistance of a step-reaction polymer comprising sulfamide and certain organic acids or their metal salts, a method of using the composition to treat the polymer and the resulting treated polymer.
摘要:
Novel perfluoroalkyl group containing mercaptans and sulfides are disclosed having soil repellent properties if applied to substrates such as textiles, paper and leather and being useful as intermediates for the synthesis of soil repellent polymers. The adducts are obtained by the base or free radical catalyzed addition of hydrogen sulfide or mono- or polymercaptans to perfluoroalkyl group containing esters of fumaric, maleic, citraconic, mesaconic, itaconic, methylene malonic or aconitic acid.
