Abstract
Copolymers having General Formula (I): in which R, R, and Rare chosen from Cto Caliphatic groups, Ris chosen from divalent Cto Clinear aliphatic groups and divalent Cto Clinear heteroaliphatic groups, optionally substituted with one or more C-Clinear aliphatic groups, C-Cbranched aliphatic groups, or combination thereof, R, R, and Rare 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).
