“…In order to improve such properties, up to now, a series of copolymers of PBS with other comonomers such as adipic acid, terephthalic acid, ethylene glycol, diethylene glycol and ε-caprolactone have been investigated [8][9][10][11][12]. These copolymers have offered opportunities in understanding the effect of comonomers on the structures and properties of the copolyesters, and developing novel polymer materials with excellent properties.…”
