Approach to nonisothermal crystallization kinetics of poly( 4‐methyl‐1‐pentene ) melt: Effect of gamma‐ray

Abstract Understanding the effect of gamma‐ray irradiation on nonisothermal crystallization polymer during cooling is practical importance for applications and manufacturing crystallized polymer. In this work, we expose poly(4‐methyl‐1‐pentene) (PMP) to with different doses study irradiated PMPs. All PMPs exhibit a doublet peak in differential scanning calorimeter thermograms rates range 2.5–20°C/min. We use linear superposition two inverse Gaussian functions decompose into individual peaks analyze kinetics processes associated peaks. The Avrami exponent decreases decrease temperature 0.96–2.43 near melting point 0.72–1.68 away temperature. activation energy increase dose. For from temperature, without smallest.
