Description

Oral presentation, abstract and conference paper
The use of enzymes as catalysts for polyesters synthesis is an attracting alternative to chemical polymerization. Several drawbacks of the traditional methods, related to traces of metal catalysts, toxicity and high reaction temperatures can be avoided using the biocatalytic route1. Poly(ε-caprolactone) is an important biocompatible polymer, but presents a number of disadvantages such as low hydrophilicity, low melting point (~60°C), and slow biodegradability rate2. Therefore, copolymerization with hydroxy-fatty acids may be an interesting approach and also a solution to improve the properties of both poly(ε-caprolactone) and of estolides.
In this work, the enzymatic synthesis of new copolymers of ε-caprolactone with four hydroxy-fatty acids, e.g. 10-hydroxystearic acid (10HSA), 12-hydroxy stearic acid (12HSA), ricinoleic acid (RCA) and 16-hydroxyhexadecanoic acid (16HHDA), was studied.
