The poly(HASCL) containing units other than 3HB and 3HV include different tercopolymers, such as poly(3HB-co-3HV-co-5HV) (R. eutropha) [90] and poly(3HB-co4HB) R. eutropha) [91]. Poly(3HB-co-3HV-co-5HV) and poly-(3HB-CO-4HB) are less crystalline and more biodegradable than poly(3HB-co-4HB). 3-Hydroxy-2,2-dimethyl-propanoic acid was polycondensed (Rhodocodus ruber) [92], as well as 3-pentenoic acid (Burkolderia) [93] and 4-pentanoic acid (Rhodospirilhum) [94] these acids were also copolycondensed with 3-hydroxy-butanoate, 3-hydroxy-pentanoate, and 3-hydroxy-2,2-dimethyl-propanoic acid. 

The reaction of the chenodeojycholic acid derivative (3-methyl-4-(3-aminohexadecahydro-7-hydroxy,10,13-dimethyl-li -cyclopentaphenan-threnyl) pentanoate with N3P3CI6 afforded the hexakis derivative (75) which was characterized hy multinuclear NMR and mass spectroscopy. ...
