Glass transition temperature ( 𝑇 𝑔 ), melting temperature ( 𝑇 π‘š ), crystallization temperature ( 𝑇 𝑐 ), and degree of crystallinity ( π‘₯ 𝑐 ) were determined from the second scan.
a 𝑀 𝑀 was calculated by the following equation: [ πœ‚ ] = 0 , 5 1 β‹… 1 0 βˆ’ 3 𝑀 𝑀 0 . 7 4 [18] by measuring [Ξ·] in H2SO4 at 20Β°C.
