DOI: 10.1016/j.compscitech.2020.108534
Abstract: ABSTRACT This work investigates the synthesis and characterisation of macrocyclic oligomers (MCO) from 4, 4’-difluoro benzophenone and catechol, their ring opening polymerisation, fabrication into carbon fibre reinforced composite materials and depolymerisation. The MCOs are polymerised… read more here.
