Abstract
A method to prepare functional polyester polyols by using micro-reaction device, wherein mixing ε-caprolactone/δ-valerolactone monomer with mercapto alcohol evenly with appropriate organic solution under moistureless conditions, and continuously transferring the prepared mixing solution into a micro-reaction device supported with an immobilized enzyme for polymerization to synthetize a poly (ε-caprolactone/δ-valerolactone). Compared with the prior art, the present invention achieves a continuous production by using immobilized lipase Novozyme435 as a catalyst.
