Preparation of a sustainable bio-copolymer based on Luffa cylindrica cellulose and poly(ε-caprolactone) for bioplastic applications
In this research, a bio-based graft copolymer (LCC-g-PCL) based on the cellulose of Luffa cylindrica (LCC) main chain possessing poly(ε-caprolactone) (PCL) pendant groups is synthesized through a grafting from approach via ring-opening polymerization (ROP). For this purpose, LCC, extracted from luffa sponges by combined method, is utilized for ROP of ε-caprolactone (ε-CL) as a macro-initiator in the presence of stannous octoate as a catalyst.
