Crystalline structure of plant resin
WebThe metallocene catalyst gives flexibility to the structure of the crystallized polystyrene SPS, allowing a variety of benzene ring arrangements. In addition, we have applied our … Crystallization of polymers is a process associated with partial alignment of their molecular chains. These chains fold together and form ordered regions called lamellae, which compose larger spheroidal structures named spherulites. Polymers can crystallize upon cooling from melting, mechanical stretching or solvent evaporation. Crystallization affects optical, mechanical, thermal and chemical properties of the polymer. The degree of crystallinity is estimated by different analy…
