Branched poly(ethylene terephthalate)s (PET) were synthesised with a variety of molar masses and with a large range of degree of branching by introduction of mono-, tri-(glycerol) and tetra-functional (pentaerythritol) comonomers to dimethyl terephthalate and ethylene glycol. The monofunctional alco
Poly(ethylene terephthalate-co-5-nitroisophthalate) copolymers, abbreviated as PETNI, were synthesized via a two-step melt copolycondensation of bis(2hydroxyethyl) terephthalate and bis(2-hydroxyethyl) 5-nitroisophthalate mixtures with molar ratios of these two comonomers varying from 95/5 to 50/50.
## Abstract Poly(ethylene isophthalateβ__co__βethylene terephthalate) (PEIPET) copolymers of various compositions and molecular weights were synthesized by melt polycondensation and characterized in terms of chemical structure and thermal and rheological properties. At room temperature, all copolym
