Structure and Properties of Biodegradable Polymers:Rolling jEffect in Polymers:Rolling Effect in Poly (butylene succinate) Sheets

摘要

Sheets made from poly (butylene succinate) were prepared by extrusion.They have been studied under uniaxial drawing as a function of the draw condition.Changes in molecular orientation and crystallinity were investigated using the criteria of differential scanning calorimetry (DSC),dynamic mechanical analysis (DMA),tensile testing,sonic modulus,X-ray diffraction,density,ensity,birefringence and measurements of% Haze.Rolling improved the thermo-mechanical and dynamic properties of extruded sheets as a result of changes in molecular orientation and crystallinity
