| titleOfInvention | Process for the production of polymethylene sulfides and their use |
| abstract | Poly (methylene sulphide) having repeating CH2S units is prepared by reacting hydrogen sulphide and formaldehyde in the presence of a catalytic amount of a water soluble metal salt of trithiocarbonic acid. Poly (methylene sulphide) containing repeating CH2S units, in the form of a free flowing white powder with a m.p. generally above 220 deg.C. The thermal stability may be improved by reacting with agents which either give terminal ethylsulphonyl, acyl, or hydrocarbyl groups, or give polymers in which the CH2S units are interrupted by these groups. The modified polymers are suitable for the prodn. of fibres, extrudates, and mouldings. |
