Abstract:
    The present invention provides a method of conjugated diene copolymer , the characteristic of the method is it make the mixture containing belowing ingredients polymerizes in the water-medium under the catalyzer of free radical polymerization; (A) 5 to 50 % of a conjugated diene compound unit, (B) 5 to 30 % of an alpha , beta -ethylenically unsaturated carboxylic acid unit, (C) 0.5 to 20 % of a polyfunctional alkenyl compound unit, (D) 0 to 20 % of a diene compound unit having cyclic carbon-carbon double bonds and (E) 0 to 60 % of a monoolefinically unsaturated compound unit. The invention also provides a photosensitive composition which comprising the conjugated diene copolymer and suited for aniline printing.
