Composition fractionation and thermal characterization of poly(3-hydroxybutyrate-co-3-hydroxypropionate)

ABSTRACT The compositional distribution has been investigated for poly(3-hydroxybutyrate-_co_-3-hydroxypropionate) [P(3HB-_co_-3HP)]s, which were microbially synthesized by _Alcaligenes

latus_ with 3-hydroxypropionic acid, sucrose or 3-hydroxybutyric acid as the sole carbon source. With a chloroform/_n_-heptane mixed solvent, they were found to be fractionated into several

fractions with different comonomer composition. It was concluded that the as-produced bacterial P(3HB-_co_-3HP) samples have a broad distribution of comonomer composition. Using the

fractions with a narrower comonomer composition distribution, the composition dependence of thermal properties and isothermal spherulite growth behavior were investigated. One of as-produced

unfractionated P(3HB-_co_-3HP) showed the DSC melting behavior refiecting that of only minor fractions with 3HP content differed remarkedly from average 3HP content of original

unfractionated P(3HB-_co_-3HP). It was concluded that each of the fractions affects thermal properties of the original P(3HB-_co_-3HP). SIMILAR CONTENT BEING VIEWED BY OTHERS THERMAL
