Investigation of the state and distribution of water in poly(ethylene terephthalate)/polyethylene glycol copolymers with various molecular weight of polyethylene glycol

Poly(ethylene terephthalate)/polyethylene glycol (PETG) copolymers with molecular weight of PEG varied from 800 to 20,000 g/mol were synthesized by melt macromolecular interesterification method. The results of contact angle and water adsorption capacity reveal that the molecular weight of PEG has a...
