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 -OR 1 , -N(R 1 ) 2 , -R 4 -OR 1 , or -R 4 -N(R 1 ) 2 , wherein R 1 is independently at each occurrence hydrogen or C 1-6 alkyl, and R 4 is C 1-12 alkylene; y is zero or 1; z is zero or 1; R 2 is C 1- 12 alkyl; and R 3 is C 1-12 alkyl when z is 1, or R 3 is C 1-12 alkyl or H when z is zero. |
