Abstract

Fibres are produced from synthetic polypeptides, of the kind described in Specification 675,298, by extruding through a jet into a setting medium a solution of the polypeptide in benzene, methylene chloride, meta-cresol, dichloracetic acid or trichloracetic acid, whereby the fibres so formed have an a molecular configuration, and then treating the fibres in a bath comprising an aliphatic mono-carboxylic acid containing from one to six carbon atoms per molecule or a like acid containing, on the a carbon atom, a bromine atom or a phenyl or mercaptan group, so that at least part of the fibres is converted into the b -molecular configuration. The synthetic polypeptides are made by polymerizing anhydro-carboxyamino-acids of the formula <FORM:0692433/IV (a)/1> R1, R2 and R3 being hydrogen or alkyl, aryl or aralkyl groups, which may be substituted or unsubstituted. Formic, acetic, propionic, normal or iso-butyric acid, normal or iso-caproic acid or crotonic acid; a -bromo acetic, propionic, butyric or n-valeric acid; phenylacetic acid or thioglycollic acid, may be used for treating the synthetic polypeptide fibres. If desired, the extruded fibres may be stretched, e.g. in steam, before the acid treatment. The polypeptide solutions may be dry or wet spun. Specified coagulants are water, methyl alcohol, ethyl alcohol and aqueous alcohols. The treatment may be carried out at room temperature for a period of 1-3 minutes. In an example, a copolymer of dl-b -phenylalanine and dl-leucine is dissolved in trichloracetic acid containing 10 per cent of water and the solution is extruded into water. The fibres so formed are passed through a bath of formic acid and then dried. The fibres obtained have a b -configuration and are insoluble in benzene or carbon tetrachloride. Other examples describe the production and treatment of fibres of copolymers of dl-b -phenylalanine with g -methyl-l-glutamate or with dl-leucine and g -benzyl-dl-glutamate. Specification 675,299 also is referred to.
