    • A polymer comprises: (a) at least one monomer residue of an aromatic dicarboxylic acid, wherein a side chain is attached from the aromatic ring and is described by formula (I) wherein Q is a substituent having a hydrophilic group, a hydrophobic group, or mixtures of; (b) at least one monomer residue of an aromatic dicarboxylic acid, an aliphatic dicarboxylic acid, or mixtures thereof; and (c) at least one monomer residue of an aromatic alcohol, an aliphatic alcohol, or mixtures thereof; wherein the monomer residues of (a), (b), and (c) are arranged to form the backbone of the polymer, and wherein the side chain of formula (I) is a pendant group extending from the polymer backbone. Preferably the polymers are polyesters containing trimellitic acid having pendant polyoxyethylene side chains. They are used as surfactants in emulsion polymerizations.
    • 聚合物包括:(a)至少一种芳族二羧酸的单体残基,其中侧链与芳环连接并由式(I)描述,其中Q是具有亲水基团的取代基,疏水基团, 或其混合物; (b)至少一种芳族二羧酸单体残基,脂族二羧酸或其混合物; 和(c)至少一种芳族醇,脂族醇或其混合物的单体残基; 其中(a),(b)和(c)的单体残基被排列成形成聚合物的骨架,其中式(I)的侧链是从聚合物主链延伸的侧基。 优选地,聚合物是含有具有侧链聚氧乙烯侧链的偏苯三酸的聚酯。 它们用作乳液聚合中的表面活性剂。
