Abstract: 1,095,147. Crimped heterofilaments. IMPERIAL CHEMICAL INDUSTRIES Ltd. June 9, 1965 [June 9, 1964], No. 23782/64. Heading B5B. Heterofilaments comprise at least two adherent polymeric components of which at least one is an elastomer and at least one other component is a non-elastomer, which heterofilaments crimp spontaneously after drawing. The components may exist in sheath-core or a side-by-side relationship. The filaments after having been drawn may have a crimp frequency of at least 10 crimps per inch and a helix diameter of less than 1 mm. The crimp in these filaments may have been developed by drawing them by an amount which exceeds the amount by which the elastomeric component may be permanently elongated by at least 20% and preferably at least 50%. The heterofilaments may be formed by melt spinning, the components being simultaneously extruded through the same or different extrusion orifices. The non-elastomeric component may be a polyamide such as poly hexamethylene adipamide, poly epsilon caprolactam or poly (11 amino undecanoic acid), a polyester such as polyethylene terephthalate or a crystalline polyolefine such as polyethylene or polypropylene. The elastomeric component may be an N-substituted polyamide prepared from a lactam of an amino-carboxylic acid and an N-substituted amino-carboxylic acid containing more than 7 carbon atoms, or a polyester urethane.

Abstract: 1,216,154. 1,2-Propenyl phosphoric acid and its salts and esters. MERCK & CO. Inc. 12 May, 1969 [15 May, 1968], No. 23970/69. Heading C2C. 1,2-Propenyl phosphonic acid or ester or salt thereof is obtained by treating allyl phosphonic acid or ester or salt thereof with a catalyst comprising a transition metal compound either in the presence of a proton-donating solvent or in the presence of an inert (e.g. a non-protondonating) organic solvent and hydrogen (preferably under pressure). The product is obtained as a mixture of the cis and trans isomers which may be separated, e.g. by column chromatography, vapour phase chromatography, or fraction-distillation or -crystallization. The transition metal catalyst may be a compound of Fe, Ni, Co, Ru, Rh, Pd, Os, Ir, Pt, Mo, Mn, or Cr and several suitable compounds are specified. The cis form of the free acid or its salts may be epoxidized to form racemic () (cis-1,2-epoxypropyl) phosphoric acid or salts thereof which have antibiotic properties. The trans compounds when subjected to further treatment with the transiton metal compound catalysts are converted to an equilibrium cis/trans mixture from which the cis isomer can be separated. The epoxidation of the cis-1,2-propenyl phosphonic acid or salt thereof may be effected by reaction with H 2 O 2  in the presence of a neutral tungstic acid salt as catalyst. Diethyl allyl phosphonate is obtained by reacting triethyl phosphite with allyl bromide. Allyl phosphonic acid is obtained by treating di-n-butyl allyl phosphonate with concentrated HCl under reflux and is converted to the sodium salt by treating with sodium bicarbonate in water. Cis-1,2-propenyl phosphonic acid is obtained by treating its diethyl (or other) ester with concentrated HCl under reflux.
