    摘要： An alkylphenol copolymer, such as for use in a petroleum composition, is provided. The alkylphenol copolymer has at least the following repeating unit (I): wherein: A is a direct bond or an alkylene; X is —C(O)O—, —OC(O)—, —C(O)N(R6)—, —N(R6)C(O)—, —C(O)—, —N(R6)—, —O—, or —S—; R6 is H or an alkyl; R1 includes a C1-C80 alkyl, a C2-C20 alkenyl, a C2-C20 alkynyl, a C3-C12 aryl, or a polyether; and n is an integer from 1 to 200. The present invention also provides a method for forming the alkylphenol copolymer containing the aforementioned repeating unit (I) as well as a method for forming a monomer for forming repeating unit (I).
