摘要

Novel renewable polyols based on limonene were synthesized using thiol-ene "click" chemistry. These limonene based polyols were structurally characterized using wet methods (hydroxyl number, acid value and viscosity), gel permeation chromatography and spectroscopic methods. The results indicated that high yield of polyols from limonene based materials can be obtained using thiol-ene reaction. These limonene based polyols were used successfully for preparation of rigid polyurethane foams. These foams had regular shape cells and uniform cell size distribution. Thermal studies on these foams indicated that foams were thermally stable up to 250 ℃. The glass transition temperature of the foams was higher than 200 ℃. These rigid polyurethane foams had high com-pressive strength and the highest compressive strength of 195 kPa was observed. These foams have good physical-mechanical characteristics and could be suitable for all the applications of rigid polyurethane foams such as thermal insulation of freezers, storage tanks for the chemical and food industries, and packing materials for food industries.
