Abstract: An acrylate copolymer, such as for use in a petroleum composition, is provided. The acrylate copolymer has the following repeating units (A) and (B): wherein, R1 and R2 are each independently H or a C1-C2 alkyl; R3 is a C8-C50 alkyl, a C8-C50 alkenyl, or a C8-C50 alkynyl; X is a divalent radical; R4 is a C4-C50 alkyl, a C4-C50 alkenyl, a C4-C50 alkynyl, a C4-C10 aryl, or —R5-R6; wherein, R5 is —C(O)O—, —OC(O)—, —C(O)—, —C(O)N(R10)—, —N(R11)C(O)—, —N(R12)—, or —O—; R6 is an alkyl, an alkenyl, an alkynyl, or an aryl; and R10, R11, and R12 are each independently H, an alkyl, an alkenyl, or an alkynyl; R13 is H, an alkyl, an alkenyl, an alkynyl, or an aryl; m is an integer from 1 to 200; and n is an integer from 1 to 200.
