𝑋 𝑐,ℎ = 𝑋 𝑐,𝑡𝑜𝑡 % 𝑊 𝐻 where WH represents the weight content of the hard segments (PBA), ΔHm is the melting enthalpy of the copolymer (PBA-DLA), and ∆Hm° is the melting enthalpy of 100% crystalline PBA (135.0 J/g) . The DSC thermograms and numerical values obtained are presented in Figure and Table , respectively.
