| abstract | 1,238,933. Alternating copolymers of maleic anhydride and conjugated dienes. BORGWARNER CORP. 17 June, 1968 [16 June, 1967], No. 28700/68. Heading C3P . The invention comprises a 1: 1 alternating copolymer of maleic anhydride and a conjugated diene. The polymer may be made by reacting the monomers in solution in an organic liquid in the presence of a high concentration of free radicals, e.g. from the thermal decomposition of azodiisobutyronitrile and tertiary butyl perpivalate. Suitable dienes are butadiene, isoprene, chloroprene, 1 - methoxybutadiene, dimethyl butadiene, piperylene, and dichlorobutadiene. The polymers preferably have more than 75% of the carbon-carbon double bond in the cis configuration. Derivatives.-The polymers may be reacted with alcohols, water, ammonium hydroxide, alkali or alkaline earth metal oxides or hydroxides, or amines. Exemplified reactants are ethyl alcohol, butyl alcohol, butoxy ethanol, to form the half ester or the diester, optionally with catalysts such as p-toluenesulphonic acid; water to form the free acid; sodium hydroxide and ammonium hydroxide to form the salts; and ammonia, butylamine, di-n-butylamine and octadecylamine to form the amide-acid. When the ammonium salt of the polymer is heated, the corresponding diene-maleimide copolymer is formed. |
