Copolymers having General Formula (I): (I) in which R1, R2, and R3 are chosen from C1 to C30 aliphatic groups, R4 is chosen from divalent C4 to C7 linear aliphatic groups and divalent C4 to C7 linearheteroaliphatic groups, optionally substituted with one or more C1-C6 linear aliphatic groups, C1-C6 branched aliphatic groups, or combination thereof, R5, R6, and R7 are each independently chosen from methyl or hydrogen, x is chosen from 0 to 0.8, y is chosen from 0 to 0.8, when y is 0, x is greater than 0, and when x is 0, y is greater than 0, and z is chosen from 0.1 to 0.9. The summation of x,y, and z equals 1. Methods for inhibiting formation of clathrate hydrates in a fluid capable of forming the clathrate hydrates, including contacting the fluid with at least one copolymer of General Formula (I). 具有通式(I)的共聚物：其中R、R和R选自C至C脂肪族基团，R选自二价的C至C直链脂肪族基团和二价的C至C直链杂脂肪族基团，任选地被个或多个C-C直链脂肪族基团、C-C支链脂肪族基团或其组合取代，R、R和R各自独立地选自甲基或氢，x选自0至0.8，y选自0至0.8，当y是0时，x大于0，并且当x是0时，y大于0，并且z选自0.1至0.9。x、y和z的总和等于1。用于在能够形成笼形水合物的流体中抑制所述笼形水合物的形成的方法，
