Abstract

Possibility of the polymerization of α-angelicalactone (5-methylfuran-2(3H)-one) via two major routes - by opening the olefin bond and/or opening of the lactone bond - is demonstrated. Polyesters of α-angelicalactone were obtained on basic catalysts. Liquid and solid polymers with the molecular masses (MM) 840 to 100 000 were synthesized. It was shown by means of NMR that the fraction of polyester intermonomer bonds in them is 60-68 %. Copolymers of α-angelicalactone with styrele additives were obtained; their ММ was about 200 000-500 000. It was shown that the obtained polymers are subject to biodegradation by different microorganisms within a time interval from a month to half a year.
