增塑剂是聚氯乙烯（PVC）生产过程中的重要助剂，能有效提高PVC的塑性。但传统邻苯二甲酸酯类增塑剂的耐久性和增塑效果有待进一步提高。本文以丁二酸、己二醇等四种不同的二元醇为原料，设计合成了多种共聚酯。采用FT-IR、H-NMR、XPS和DMA等方法对该树脂的增塑性能进行了表征。研究发现，增塑剂结构单元中的侧链基团对其塑化性能有很大的影响。聚丁二酸丁二醇酯3-氯-1，2-丙二醇酯（PSCH）增塑PVC的玻璃化转变温度比DOP增塑PVC的玻璃化转变温度降低8.1 ℃，断裂伸长率提高104.7%。与DOP相比，具有柔性长链烷烃和极性C-Cl基团的可调增塑剂具有改善的耐溶剂萃取性和更好的增塑剂与PVC之间的相容性。通过FT-IR、XPS和溶解度参数DS分析，证实了增塑剂C=O基团与PVC α-氢之间的氢键作用是PSCH对PVC有效增塑的主要原因。
Plasticizer is an important assistant in the production process of polyvinyl chloride (PVC), which can effectively improve the plasticity of PVC. However, the durability and plasticizing effect of traditional phthalate plasticizers need to be further improved. In this paper, a variety of copolyesters are designed and synthesized from succinic acid, hexanediol and other four different diols. The plasticizing performance of the copolyester is characterized by FT-IR, H-NMR, XPS and DMA. It is found that the side chain groups in the structural units of the copolyester have a great influence on its plasticizing properties. The glass transition temperature of PVC plasticized by polybutylene succinate 3-chloro-1,2-propanediol ester (PSCH) is 8.1 ℃ lower than the temperature of PVC which is plasticized by DOP, and the elongation at break is increased by 104.7%. The obtained copolyester plasticizer with flexible long alkane chains and polar C–Cl groups shows improved solvent extraction resistance and better compatibility between plasticizer and PVC compared DOP. It is verified that the hydrogen bonding interaction between the C=O group of plasticizers and α-hydrogen of PVC exhibited in FT-IR, XPS and solubility parameters DS is the main reason for the effective plasticizing efficiency of PSCH on PVC.
