STACKING-SPIRALIZED POLY-ORTHO-PHENYLENE HYDROXYLATED AT POSITIONS 3, 5, 6 AND METHOD OF ITS SYNTHESIS Russian patent published in 1997 - IPC

Abstract RU 2085559 C1

FIELD: chemical technology, polymers. SUBSTANCE: invention relates to stacking-spiralized poly-o-phenylene hydroxylated at positions 3, 5 and 6 at polymerization degree 3-10. Polymer is synthesized by polymerization of p-benzoquinone in air in the presence of alkali 10-35% of benzoquinone mass followed by treatment with alkali in inert medium at amount 90-110% of benzoquinone mass. Synthesized polymer enhances antiviral resistance. EFFECT: improved method of synthesis. 3 cl, 4 tbl
