A polymer comprises randomly distributed units UA, UB, UC and UD and at least one unit bearing a subunit F according to the respective molar percentages m, n, o, p and f
F pendant along the chain of the polymer and bearing an associative group comprising at least one nitrogen atom,
R1 and R2, which are identical or different, denoting a hydrogen atom, a methyl radical or a phenyl radical which is unsubstituted or substituted in the ortho, meta or para position by a methyl radical,
m≥50, n≥0, o≥0, f>0, 0<0+p≤25, m, n, o, p and f ranging from 0 to 100, the respective molar percentages of m, n, o, p and f calculated based on the sum of m+n+o+p+f, which is equal to 100.

F 沿聚合物链悬垂,并带有至少一个氮原子组成的连接基团、
相同或不同的 R1 和 R2,表示氢原子、甲基或未被甲基取代或在正位、偏位或对 位被甲基取代的苯基、
m≥50,n≥0,o≥0,f>0,0<0+p≤25,m、n、o、p 和 f 的范围为 0 至 100,m、n、o、p 和 f 各自的摩尔百分比根据 m+n+o+p+f 之和计算,该和等于 100。
