Abstract: | Pseudomonas putida was grown on a mixture of long-chain fatty acids obtained by hydrolysis of linseed oil. A poly(3-hydroxyalkanoate) containing
51.2% of unsaturated monomers was obtained. A considerable percentage (13.6%) was constituted by C14 and C16 monomers containing three double-bonds in the side chains. The polymer showed a high tendency to crosslink when it was kept
in presence of air. In the crosslinked polymer no polyunsaturated monomers could be detected. |
