    • Trisequenced copolymer A-B-C with an Mn from 3 000 to 300 000 and a polydispersity from 1.05 to 2.0, A and C both being an acrylic, vinylaromatic, methacrylic or maleimide sequence, B being an acrylic, vinylaromatic or methacrylic sequence, at least one of A or C being chosen in a different class from that of group B. To prepare the copolymer, anionic polymerisation is carried out on at least one A monomer, with the help of an initiator system formed by at least one monofunctional initiator (R)p-M (M = alcaline metal or alcaline earth metal, p = valence of M, and R = C2-6 alkyl or C1-6 alkyl substituted by at least one phenyl group), and at least one ligand (a salt of an alcaline metal or an alcaline earth metal). The live link A obtained with at least one B monomer is made to react; the copolymer (A-B) obtained is made to react with at least one C monomer, and the copolymer (A-B-C) obtained is made to react with at least one protolytic compound. If A and C are identical, a bifunctional initiator is used during the first stage.
    • 三分相共聚物ABC,Mn为3 000至300 000,多分散性为1.05至2.0,A和C均为丙烯酸,乙烯基芳族化合物,甲基丙烯酸或马来酰亚胺序列,B为丙烯酸,乙烯基芳族或甲基丙烯酸序列,A至少之一为 或C选自与B组不同的类别。为了制备共聚物,借助于由至少一种单官能引发剂(R)pM(R)形成的引发剂体系,在至少一种A单体上进行阴离子聚合 M =碱金属或碱土金属,p = M的价数,R = C 2-6烷基或被至少一个苯基取代的C 1-6烷基)和至少一种配体(碱金属或 碱土金属)。 使用至少一种B单体获得的活链A < 使所得的共聚物(A-B)与至少一种C单体反应,使所得的共聚物(A-B-C)与至少一种原酸化合物反应。 如果A和C相同,则在第一阶段使用双功能引发剂。
