Production method of polyester containing epoxy group in side chain and production method of crosslinked polymer

摘要

A method is provided which biosynthesizes a PHA having an epoxy group in a side chain terminal with improved physicochemical properties. Specifically, a method of producing a polyester containing an epoxy group in a side chain thereof using 1-alkene as a raw material is provided which comprises the steps of bringing 1-alkene into contact with a microorganism having an ability to uptake 1-alkene and convert it to a polyester and allowing the microorganism to convert the 1-alkene into a polyester containing an epoxy group in a side chain thereof. Further, a method of producing a crosslinked polymer is provided which comprises reacting the polyester obtained by the above mentioned method with a diamine compound.
