▎ 摘  要

NOVELTY - Isopentane derivative (I) and silicon-containing compound (II) are reacted at 120-200 degrees C in presence of carboxylic acid (III) to obtain diisopentane derivative (IV). Diisopentane derivative (IV) is processed to obtain diisopentane derivative (V). Diisopentane derivative (V) and 11-hydroxy-11,13-dihydroovalene-2-carboxylic acid (VI) are reacted at 150-200 degrees C to obtain graphene-grafted polyolefin (VII). USE - Preparation of graphene-grafted polyolefin used for composite material. ADVANTAGE - The method enables preparation of graphene-grafted polyolefin by simple method. The composite material containing graphene-grafted polyolefin has excellent toughness, rigidity and strength, and high thermal deformation temperature. DETAILED DESCRIPTION - Isopentane derivative of formula (I) and silicon-containing compound of formula (II) are reacted at 120-200 degrees C in presence of carboxylic acid of formula: R1COOR2 (III) to obtain diisopentane derivative of formula (IV).
