A curable composition includes a hydrogen-bonded prepolymer, a plasticizer, and, optionally, a crosslinking agent. The plasticizer includes a reactive plasticizer having structure (I), (II), or (III), wherein X is —OR1, —N(R1)2, —R4—OR1, or —R4—N(R1)2, wherein R1 is independently at each occurrence hydrogen or C1-6 alkyl, and R4 is C1-12 alkylene; y is zero or 1; z is zero or 1; R2 is C1-12 alkyl; and R3 is C1-12 alkyl when z is 1, or R3 is C1-12 alkyl or H when z is zero.
一种可固化组合物包括氢键预聚物、增塑剂和可选的交联剂。增塑剂包括具有结构(I)、(II)或(III)的反应性增塑剂,其中 X 为-OR1、-N(R1)2、-R4-OR1 或-R4-N(R1)2,其中 R1 在每次出现时独立地为氢或 C1-6 烷基,R4 为 C1-12 亚烷基;y 为零或 1;z 为零或 1;R2 为 C1-12 烷基;当 z 为 1 时,R3 为 C1-12 烷基,或当 z 为零时,R3 为 C1-12 烷基或 H。
