Abstract
Products suitable for conversion into filaments, yarns, and ribbons are obtained by reacting synthetic polymers or copolymers of dienes with sulphur dioxide or sulphurous acid in the presence of organic or inorganic hydroperoxides. The polymeric substances must have a molecular weight of at least 5,000, and contain a plurality of unsaturated carbon to carbon linkages in the molecule. Specified substances are polymers of butadiene, methyl butadiene, dimethyl butadiene, and pentadiene; and copolymers of these monomers with isobutene. A hydroperoxide is defined as having the group R-O-O-H where R is a hydrogen atom or an organic radical in which a carbon atom of the radical is directly attached to the group O-O-H. Specific hydroperoxides are tetrahydro-naphthalene peroxide, peracetic acid, tertiary butyl hydroperoxide and hydrogen peroxide. In an example a butadiene polymer in benzene solution was coagulated by peracetic acid and sulphur dioxide dissolved in alcohol and water. Specifications 527,075 and 611,919 are referred to. The Specification as open to inspection under Sect. 91 comprises also the use, in the place of the polymeric substances specified, of polymerized chloroprene and acetylene; and copolymers of butadiene, methyl butadiene, dimethyl butadiene, pentadiene, chloroprene and acetylene with acetylene, vinyl acetylene, isobutene, styrene, vinyl chloride, vinyl esters, acrylic acid, methacrylic acid, methyl isopropenyl ketone, or vinyl ethyl ether. In addition the sulphur dioxide may be replaced by any inorganic acid or inorganic acid excepting those in which the acid forming element occurs in the highest valency in cases in which more than one series of such compounds may be formed. Specified substances of this type are phosphorous trioxide, hydrogen sulphide, hydrochloric acid, and hydrobromic acid. This subject-matter does not occur in the Specification as accepted.ALSO:Products suitable for conversion into filaments, yarns, and ribbons are obtained by reacting natural or synthetic polymers or copolymers of dienes with sulphur dioxide or sulphurous acid in the presence of organic or inorganic hydroperoxides. The polymeric substances must have a molecular weight of at least 5,000, and contain a plurality of unsaturated carbon to carbon linkages in the molecule. Specified substances are natural rubber, polymers of butadiene, methyl butadiene, dimethyl butadiene and pentadiene; and copolymers of these monomers with isobutene. A hydroperoxide is defined as having the group R-O-O-H where R is a hydrogen atom or an organic radical in which a carbon atom of the radical is directly attached to the group O-O-H. Specific hydroperoxides are tetrahydro-naphthalene peroxide, peracetic acid, tertiary butyl hydroperoxide and hydrogen peroxide. In examples (1) A rubber in benzene solution containing tetrahydro naphthalene peroxide was coagulated by sulphur dioxide dissolved in alcohol and water (ii) A butadiene polymer in benzene solution was coagulated by peracetic acid and sulphur dioxide dissolved in alcohol and water. (iii) and (iv) Gaseous sulphur dioxide was passed into a benzene solution of rubber containing either tertiary butyl hydroperoxide in butyl alcohol or hydrogen peroxide in diethyl ether. Specifications 527,075 and 611,919 are referred to. The Specification as open to inspection under Sect. 91 comprises also the use, in the place of the polymeric substances specified, of polymerised chloroprene and acetylene; and copolymers of butadiene, methyl butadiene, dimethyl butadiene, pentadiene, chloroprene and acetylene with acetylene, vinyl acetylene, isobutene, styrene, vinyl chloride vinyl esters, acrylic acid, methacrylic acid, methyl isopropenyl ketone, or vinyl ethyl ether. In addition the sulphur dioxide may be replaced by any inorganic acid or inorganic acid excepting those in which the acid forming element occurs in the highest valency in cases in which more than one series of such compounds may be formed. Specified substances of this type are phosphorous trioxide, hydrogen sulphide, hydrochloric acid, and hydrobromic acid. This subject-matter does not appear in the Specification as accepted.
