Abstract
Solutions of polybutadiene of average molecular weight between 10,000 and 80,000 (determined as described on page 660 of "Rubber Chemistry and Technology, July 1949") are extruded into solutions of sulphur dioxide to form filaments, ribbons and other shaped articles. The polybutadiene solutions may be of concentration between 5 and 25 per cent. by weight, and of viscosity between 10 and 1,000 centipoises. The solvent used may be benzene, toluene or an ether and it may contain an activator such as tetralin hydroperoxide. Suitable solvents for the sulphur dioxide include mixtures of ethanol and water or aromatic hydrocarbons, e.g. toluene. Specifications 663,645, [Group VIII], and 666,644 are referred to.ALSO:Solutions of polybutadiene of average molecular weight between 10,000 and 80,000 (determined as described on p. 660 of "Rubber Chemistry and Technology," July, 1949) are extruded into solutions of sulphur dioxide to form filaments, ribbons and other shaped articles. The polybutadiene solutions may be of concentration between 5 and 25 per cent. by weight, and of viscosity between 10 and 1,000 centipoises. The solvent used may be benzene, toluene or an ether solvent, and it may contain an activator such as a hydrocarbon hydroperoxide. Suitable solvents for the sulphur dioxide include mixtures of ethanol and water (e.g. in weight ratio 4 : 1) and mixtures of ethanol and aromatic hydrocarbons (in weight ratio 2 : 1). In an example a number of toluene solutions of polybutadiene samples, each of a different p average molecular weight and all of viscosity about 210 centipoises after addition of 15 per cent. (based on the weight of the polybutadiene) of tetralin hydroperoxide, are extruded into solutions of sulphur dioxide in mixtures of equal volumes of ethanol and toluene containing 100 g. SO2/litre. The spinning temperature is 20 DEG C. Specifications 663,645. [Group VIII], and 666,644 are referred to.
