Direct Fabrication of Porous Isotactic Poly-1-Butene With Form I From the Melt Using CO2
The deformation of isotactic poly-1-butene (iPB-1) matrix, during the CO2-assisted foaming process, makes the iPB-1 melt crystallize into form I rather than form I', which crystallizes after annealing under high-pressure CO2 without foaming. The result provides a new strategy to directly obtain porous iPB-1 with stable form I from iPB-1 melt.
