Title: Fibre-forming linear polymers
IPC: C08G63/54
Filed: 1950-08-22
Abstract: A fibre-forming linear polymer is made by heating a stilbene dicarboxylic acid compound with at least one bifunctional compound of the group HO-R-OH, H2N-R-NH2 and HO-R-NH2, wherein R is an alkylene, cycloalkylene, arylene or alkarylene radical containing from 2 to 16 carbon atoms. Another dibasic acid compound may also be included in the reaction mixture.  Stilbene dicarboxylic acid compounds include the different isomers of the acid and the polyester- and polyamide forming derivatives, the polyester - forming-derivatives specified being the methyl, ethyl, propyl, butyl, amyl, hexyl, heptyl and octyl stilbene dicarboxylates and esters derived from cyclopropyl carbinol, cyclobutanol, cyclopentanol, cyclohexanol, phenol, cresols and benzyl alcohol.  Bifunctional compounds specified are ethylene- and 1,4-butylene-glycols, hydroquinone, xylylene glycol, 1 : 4-dihydroxy cyclohexane, polymethylene glycols containing 2 to 10 carbon atoms, ethylene-, tetramethylene and hexamethylene diamines, and amino-ethyl-, -propyl-, -butyl-, and -amyl-alcohols.  Dibasic acid compounds specified are succinic, adipic, suberic, fumaric and maleic acids, cyclopentane-, and cyclohexane-dicarboxylic acids, terephthalic acid and dibenzyl dicarboxylic acid.  The reaction is usually effected in an atmosphere of nitrogen at 200 DEG  to 350 DEG C. and in the presence of an esterification catalyst, e.g. hydrogen chloride, p-toluene sulphonic acid, and lithium, sodium and magnesium powder, chips or shavings.  In examples: (1) p,p1-stilbene-dicarboxylic acid is reacted with ethylene glycol in the presence of conc. sulphuric acid to give a brown, flexible, rubbery mass, which can be drawn into threads and filaments.  These exhibit a blue fluorescence upon insolation; the diethyl ester of p,p1-stilbene dicarboxylic acid is reacted, in the presence of sodium and magnesium, with (3) ethylene glycol to give a fluorescent solid; (4) ethylene glycol and polyethylene terephthalate; (5) 1,5-pentanediol; and (6, 7) ethylene glycol and dimethylterephthalate to give, when extruded, a fluorescent fibre.  The polymers may be used in conjunction with other linear polyesters and polyamides and with the usual additives.  Modified polymers may be made by reaction, before or after polymer formation, with compounds capable of adding across or reacting with a double bond, e.g. halogens, hydrogen peroxide, potassium permanganate, hydrogen halides, hypohalites, organic acids, maleic acid.  The polymers find use in the preparation of yarns and fabrics, coatings, moulding compositions, films and bristles.

Filed: 1945-08-14
Abstract: 608,135. Photo-mechanical printing-surfaces. POWERS, F. T. Aug. 14, 1945, No. 20878. [Class 98 (ii)] In the process of preparing photo-mechanical printing-surfaces which includes the steps of coating a surface to be etched with a lightsensitive resist of glue or gelatin sensitized by a chromic acid salt, exposing the resist to a light image and developing to remove the parts not acted on by light, the exposed resist is subjected to the additional step of treatment with a substantive dye and a hardening compound before, during, or after development. The term " substantive dye is used in its usual meaning as defining that group of dyes which dye cotton without the application of a mordant or fixing agent. Brilliant benzoechtviolett (Schultz) is an example. As hardening compound chromic acid is preferred, but the acids of vanadium, tungsten, molybdenum and manganese, chrome alum, tannic acid or sodium bisulphite may be used. The dye and the hardening compound are applied to the resist together or separately in aqueous solution. In a modification, a solution containing a non- oxidizing reversible hardening agent which will not combine with the glue or gelatin may be utilized as an additional treating bath for the exposed resist before, during or after development and such agent may be ferric ammonium citrate, ferric citrate, uranium citrate, aluminium chloride or iron alum, and a small quantity of alkali such as sodium hydroxide may be added to the non-oxidizing reversible hardening agent. The treatment is stated to harden the edges of the dots or lines of the developed image to a greater extent than the interior of the dots or lines and to render the step of burning-in of the dried resist unnecessary.
