Title: Coated threads or the like of synthetic linear polyamide resin
IPC: D06M15/244
Filed: 1946-05-02
Abstract: <PICT:0628466/IV (c)/1> A thread, cord, or the like comprises a core of previously cold drawn synthetic linear polyamide of high tensile strength and low elongation and a covering of polyvinyl chloride extruded on to the core to form a continuous covering protecting the core against moisture and friction.  As shown the polyvinyl chloride is forced under pressure through conduit 2 to the extrusion die 4 so as to coat the nylon thread 7 with a covering 6.  The composite thread may be used for making boot laces, harness for artillery equipment, cables for aircraft controls, or cords for spindles. The thread may be milled to improve the resistance against friction. Specification 634,071, [Group XXX], is referred to.  The Specification as open to inspection under Sect. 91 comprises also composite threads in which the coating is of artificial or natural rubber, or cellulose acetate.  This subject-matter does not appear in the Specification as accepted.

Title: Method of further polymerising liquid organo-polysiloxanes
Filed: 1956-05-07
Abstract: Liquid dialkylpolysiloxanes are further polymerized to organic solvent-soluble gels convertible to the solid, elastic state, by reacting them with an aluminium compound containing at least one aluminium-bonded alkyl radical at temperatures between room temperature and 60 DEG  C.  The reaction may be effected in the presence of a solvent or liquid diluent and is enhanced by the addition to the reaction mixture of compounds containing active hydrogen, e.g. organic and inorganic acids, alcohols, phenols, thiophenols and water, or by atmospheric moisture.  In examples, liquid dimethylsiloxane is polymerized to a gel (1 to 5, 7) by aluminium triethyl, hexane being used as a solvent in (2), and atmospheric moisture being used in (5, 7); and (6) by the compound (C2H5)2 AlOSi(CH3)3 and water.

The diacarboxylic acids may contain 6 to 20 carbon atoms, aliphatic dicarboxylic acids may contain at least 4 carbon atoms between carboxyl groups and aromatic or alicyclic dicarboxylic acids, 3 carbon atoms between the carboxyl groups. In preferred embodiments, salts obtained by mixing substantially equivalent amounts of dicarboxylic acid and aromatic diamine are heated in a purged sealed vessel at 200-300‹ C. for 30 to 90 mins. to form a prepolymer. The M.W. of the latter is increased by either stirring a melt at 200-350‹ C. for ¢ to 3 hours in vacuo or by granulating the prepolymer to a particle size of 0À03 in. or smaller and heating in vacuo at a temp. below the m.p. of the prepolymer.
