There has been a growing interest in reactive crystallizable polyesters/noncrystallizable polyethers blends for adhesive and coating applications. The aliphatic polyesters are employed to control viscosity and mechanical property through crystallization and the polyethers are to provide elasticity and impact strength at the temperature ranges applied. For those blend systems, viscosity and reactivity control is important. As expected, the viscoelastic mechanical response and curing reaction of immiscible and crystallizable polymer blends is a complex function of a variety of microstructural features such as liquid/liquid phase-separated structure, interface between domains and matrix, degree of crystallinity, and crystallite shape. In this current study, viscoelastic physical gelation and curing reaction associated with microstructural development of immiscible and crystallizable polymer blends are investigated. |
