▎ 摘　　要

NOVELTY - Styrene-maleic anhydride copolymer functionalized graphene oxide modified vinyl ester resin (I) is new. USE - (I) is useful for preparation of marine anticorrosion coatings (claimed). ADVANTAGE - (I): ensures the cured film obtained by curing the styrene-maleic anhydride copolymer functionalized graphene oxide modified vinyl ester resin has excellent barrier properties, low surface energy, good corrosion resistance and excellent mechanical properties. The preparation method: has one-pot method, simple process, and high raw material utilization rate. DETAILED DESCRIPTION - Styrene-maleic anhydride copolymer functionalized graphene oxide modified vinyl ester resin of formula (I) is new. R1= aryl moiety of formula (1a); R2= CH2=CH-C(=O)-O-CH2-CH2-O-CH3, CH2=C(CH3)-C(=O)-O-CH2-CH2-O-CH3or CH2=CH-C(=O)-O-CH2-CH2-CH2-O-CH3; and m:n = 3:1-5:1. An INDEPENDENT CLAIM is also included for preparation of (I).
