The processing, structure and properties of poly(1-butene) monofilaments

An investigation into the structure and properties of poly(1-butene) monofilaments was carried out. Eight commercial grades of poly(1-butene) were thoroughly characterized and compared by a wide range of techniques: DSC, GPC, C13nmr, melt rheology, optical and electron microscopy, crystallization rates and crystallinity were also measured. Both qualitative and quantitative information was obtained on additives, blends, copolymers and polymer tacticity. To compare the mechanical properties of the materials in the absence of molecular orientation at various levels of crystallinity compression moulded sheets were produced. [Continues.]
