Abstract

1357208 Polyamides STAMICARBON NV 29 Nov 1971 [5 Dec 1970 15 May 1971] 55215/71 Heading C3R A process for preparing particulate polyamide comprises polymerizing at least one lactam having at least 6 ring carbon atoms in a solution thereof in an inert solvent for the lactam which is not a solvent for the resulting polyamide at a temperature below the melting point of the polyamide using an anionic catalyst and bis-#- caprolactim ether as promoter. A fibrous and/or powder filler may be present during polymerization. Specified materials are lactams:- capro-, oenantho-, capryl- and lauro-lactams, substituted lactams and lactams having ether or thioether links in the ring; solvents:- toluene, xylenes, gasolines of boiling range 80‹ to 140‹ C., tetramethylpentane, pentamethylheptane and tetralin; fillers:-powdered or fibrous Fe, Cu, Ni, Ti, V, Cr, Co, or Al; boron; quartz, feldspar, granite, asbestos, mica, slate, dolomite, talc or cristobalite; graphite, carbon black or carbon fibres; oxides of B, Al, Ti or Mg; carbides, carborundum, borides or silicates; glass fibres or wool; inorganic pigments; thermoset resins e.g. phenol-formaldehyde; and thermoplastic resins which do not significantly soften at the reaction temperature, e.g. polyamides or P.T.F.E. Spherical fillers may have a diameter of 10Š to 1 cm. and fibrous fillers a diameter of 0À5 to 100 Á and length of 5 Á to 2 cm. The process is stated to give products of narrow grain size distribution with consequent high density (1À172 to 1À176 g./ml. in examples); M w 20,000 to 100,000; and high notch impact strength in conjunction with high E-modulus. Reference is made to Specifications 1,022,669, 1,058,492, 1,118,700 and 1,211,083.
