| abstract | 1,146,553. Graft polymers modified with polyamides. FOSTER GRANT CO. Inc. 11 Jan., 1967, No. 1627/67. Headings C3G and C3R. A thermoplastic, fibre-forming graft polymer is derived from (i) a first graft copolymer, which comprises a monovinyl (including monovinylidene) aromatic compound grafted on to an unsaturated hydrocarbon polymer having a weight average molecular weight of from 500 to 50,000, the macromolecular backbone chain of the unsaturated hydrocarbon polymer having two or more carboxyl groups attached thereto, at least one of which is an end group, and (ii) lactam having at least six atoms in the lactam ring, wherein the fibre-forming graft polymer contains from 5 to 50 weight per cent of the monovinyl aromatic compound based on the total amount of the lactam incorporated in the fibre-forming polymer, the combined weight of the monovinyl aromatic compound and the lactam being in the range of from 95À0 to 99À9% by weight of the total weight of the fibreforming graft copolymer. The unsaturated hydrocarbon polymer is preferably derived from a C 4 to C 6 -diene. The lactam, e.g. caprolactam, 2-oxo-pentamethyleneimine, 2 - oxo -heptameth - yleneimine, 2-oxo-octamethyleneimine or 2- oxo-decamethyleneimine may be reacted with the first graft polymer in the presence of a catalyst comprising water, an organic compound which liberates water under the reaction conditions, or aminocaproic acid. The examples illustrate a process in which (i) styrene is grafted on to a liquid polybutadiene having a carboxyl group at each end of the polymer molecule in the presence of tert.-butyl peracetate and molten caprolactam to form the first graft polymer and (ii) the temperature of the reaction mixture is raised, additional caprolactam and water are added and reaction carried out to yield the fibre-forming graft polymer. This process is modified (a) by partly replacing the styrene with alpha-methylstyrene or wholly replacing it with a mixture of o- and p-chloro. styrenes, or with p-methylstyrene or (b) by replacing the caprolactam with caprylactam or dodecalactam. |
