Transesterification of triacetin by aminated fibrous polymer catalyst in a batch process

A solid polymer catalyst in a form of fibrous ion exchange resin containing basic functional groups was prepared by amination of (chemical treatment with triethylamine) with a copolymer of glycidyl methacrylate (PGMA) and polyethylene (PE) (PE-g-PGMA) having 600 % degree of grafting. The PE-g-PGMA (...
