聚羟基烷酸(PHA)共聚物由(R)-3-羟基丁酸酯(3HB)和中链(R)-3-羟基烷酸(3HA)组成，P(3HB-co-3HA)通常溶于氯仿。然而，我们发现，一些在常温下老化1个月以上的P(3HB-co-3HA)不能在氯仿中溶解，而是在3HA含量超过14%时发生溶胀。根据差示扫描量热法和广角X射线衍射仪的分析，我们预测了可溶胀的P(3HB-co-3HA)中含有大量的P(3HB)微晶，这些微晶可能在相邻的PHA高分子链之间形成物理交联。
Polyhydroxyalkanoate (PHA) copolymers consisting of (R)-3-hydroxybutyrate (3HB) and medium-chain-length (R)-3-hydroxyalkanoate (3HA), P(3HB-co-3HA), are usually solved in chloroform. However, we found that some of the P(3HB-co-3HA) aged for more than 1 month under ambient conditions were not solved in chloroform, but instead swelled when the 3HA fraction was over 14 mol%. On the basis of differential scanning calorimetry and wide-angle x-ray diffraction analyses, we predicted that swellable P(3HB-co-3HA) contained numerous P(3HB) microcrystals, which may form physical crosslinks between adjacent PHA polymer chains.
