Study of the high temperature HYDROLYSIS of POLY(EPSILON-CAPROLACTONE)

To study the hydrolytic degradation of poly(ε-caprolactone) (PCL) some samples were kept in water for some days and were weighed daily to determine the weight evolution. In order to accelerate the natural process of hydrolysis the samples were maintained in a heated thermal bath. From this work it was possible to conclude that the hydrolysation of PCL occurs at high temperatures, around and slightly under its melting point, and that the hydrolysation rate is slightly smaller at 50oC than at 60oC.
