Degradation of Polycaptolactone Modified with TPS or CaCO3 in Biotic/Abiotic Sewater

Abstract

The polymer degradation process in two types of water sourced from the Baltic Sea was investigated. Polycaprolactone modified with thermoplastic starch(PCL/TPS>85%) or calcium carbonate (60% PCL/40% CaCO3)and PCL alone were incubated for 28 weeks in sea water with and without microrganisms. The experimental results indicated that in each of the experiments degradation occured. The process was more effective in sea water with microorganisms.Modification of PCL with CaCO3 did not encourage the degradation process; in some circumstances inhibited it.
