| description | The aliphatic-aromatic polyester resin has main structural units of an aliphatic dicarboxylic acid unit, an aromatic dicarboxylic acid unit, and an aliphatic diol unit and/or an alicyclic diol unit, the abundance ratio (molar ratio) of the aliphatic dicarboxylic acid unit to the aromatic dicarboxylic acid unit being 15: 85-85: 15, and the glass transition temperature being-25 DEG C or higher. And has a branched structure represented by formulae (1) to (4). (In formulae (1) to (4), Ar1, Ar2, and Ar3 each independently represent a C4-12 divalent aromatic hydrocarbon ring group or aromatic heterocyclic group which may have a substituent. And R represents a hydrogen atom or an alkyl group having 1-4 carbon atoms. And each of n, m and r independently represents an integer of 2-10).
一种脂肪族-芳香族聚酯树脂，其主要结构单元为脂肪族二羧酸单元、芳香族二羧酸单元，以及脂肪族二醇单元和/或脂环式二醇单元，该脂肪族二羧酸单元与该芳香族二羧酸单元的存在比率(摩尔比)为15：85～85：15，玻璃化转变温度为-25℃以上，且具有下述式(1)～(4)所表示的支化结构。(式(1)～(4)中，Ar1、Ar2、Ar3分别独立地表示可具有取代基的碳原子数4～12的2价芳香族烃环基或芳香族杂环基。R表示氢原子或碳原子数1～4的烷基。n、m、r分别独立地为2～10的整数 |
