AbstractNon-ionic aliphatic polymers containing ester and sulfonyl moieties, poly(ester-sulfones) were found to show anode-selective electrophoresis under electrophoretic deposition (EPD) conditions. Various polyesters containing a sulfide linkage were prepared via low-temperature polycondensation using scandium trifluoromethanesulfonate [Sc(OTf)3] as a catalyst in order to clarify the relationship between the chemical structure and the electrophoresis. Subsequently, oxone oxidation was carried out in order to obtain the expected saturated and unsaturated poly(ester-sulfone)s, and electrophoretic deposition (EPD) of the poly(ester-sulfone) onto stainless steel was performed. For unsaturated poly(ester-sulfone) onto stainless steel, subsequent UV irradiation cured the deposited film, improving the peeling strength of the coating.Graphical AbstractVarious polyesters containing a sulfide linkage were prepared via low-temperature polycondensation using scandium trifluoromethanesulfonate [Sc(OTf)3] as a catalyst in order to clarify the relationship between the chemical structure and the electrophoresis.

通过低温缩聚反应合成非离子聚（酯-砜）用于阳极选择性电泳沉积和随后的光交联

摘要发现含有酯和磺酰基部分的非离子脂肪族聚合物聚（酯-砜）在电泳沉积 (EPD) 条件下显示出阳极选择性电泳。为了阐明化学结构与电泳之间的关系，使用三氟甲磺酸钪[Sc(OTf)3]作为催化剂，通过低温缩聚反应制备了各种含硫键的聚酯。随后，进行oxone氧化以获得预期的饱和和不饱和聚（酯-砜），并进行聚（酯-砜）在不锈钢上的电泳沉积（EPD）。对于不锈钢上的不饱和聚（酯-砜），随后的紫外线照射固化了沉积的薄膜，提高了涂层的剥离强度。图解摘要为了阐明化学结构与电泳之间的关系，以三氟甲磺酸钪[Sc(OTf)3]为催化剂，通过低温缩聚反应制备了各种含硫键的聚酯。随后，进行oxone氧化以获得预期的饱和和不饱和聚（酯-砜），并进行聚（酯-砜）在不锈钢上的电泳沉积（EPD）。对于不锈钢上的不饱和聚（酯-砜），随后的紫外线照射固化了沉积的薄膜，提高了涂层的剥离强度。并在不锈钢上进行聚（酯-砜）的电泳沉积（EPD）。对于不锈钢上的不饱和聚（酯-砜），随后的紫外线照射固化了沉积的薄膜，提高了涂层的剥离强度。并在不锈钢上进行聚（酯-砜）的电泳沉积（EPD）。对于不锈钢上的不饱和聚（酯-砜），随后的紫外线照射固化了沉积的薄膜，提高了涂层的剥离强度。
