Abstract: Abstract Temperature Rising Elution Fractionation (TREF) is effective for separating polyolefin resins according to crystallizability. A relatively low isothermal crystallization temperature is necessary to fractionate poly(1-butene) (PB-1) resin because of its slow crystallization kinetics. This… read more here.

Abstract: Isotactic poly(1-butene) (iPB-1) is a high performance plastic with outstanding properties, such as flexibility, superior creep, environmental stress cracking and abrasive resistance. However, it exhibits a complex crystal polymorphism and polymorphic transformation behavior, which has… read more here.

DOI: 10.1122/1.5021000
Abstract: Intervals of shear flow can induce the formation of crystallization precursors, thereby facilitating crystallization of semicrystalline polymers. This effect can be gradually removed through annealing the presheared samples at high temperature. This study compares the… read more here.
