Abstract Rice husk ash is a side-product of rice production; thus, it is a cheap, abundant, and renewable
material, and utilized as an enzyme carrier to immobilize Candida antarctica lipase B. In this
study, Candida antarctica lipase B immobilized onto rice husk ashes was used to catalyze ring
opening polymerization of 16-membered lactone, ω-pentadecalactone. In order to determine
the best polymerization conditions for highest molar mass polymer, reactions were proceeded
at various temperatures and time periods. The best reaction conditions were obtained as 80°C
and 6 hours (Mn
= 34255 g mol-1). Molecular structure of this polymer More >
