摘要：NOVELTY - Benzoxazine graft-modified poly(p-phenylene-2,6-benzoxazole) polymer (PBO) (I) is new. USE - New benzoxazine graft-modified poly(p-phenylene-2,6-benzoxazole) polymer for producing modified poly(p-phenylene-2,6-benzoxazole) polymer fibers. ADVANTAGE - The fibers formed of new benzoxazine graft-modified poly(p-phenylene-2,6-benzoxazole) polymer has excellent compression resistance. DETAILED DESCRIPTION - Benzoxazine graft-modified poly(p-phenylene-2,6-benzoxazole) polymer of formula (I) is new. n+m=100 mol%; n=80-95 mol%; m=5-20 mol%;and R=group of formula (i)-(iv). An INDEPENDENT CLAIM is included for preparation of benzoxazine graft-modified poly(p-phenylene-2,6-benzoxazole) polymer (I).
