The kinetic crystallization study is a key matter for polymeric materials processing, since the material properties are impacted by crystalline content and morphology. It's well know that crystalline phase plays an important role in tensile and impact strength. Even though the kinetics of isothermal crystallization has been extensively investigated, practical processes, such as industry operations, proceed under non-isothermal conditions and isothermal crystallization are seldom applied. This work consists in a kinetic of non-isothermal crystallization study of polyethylene/calcium phosphate composites, a material with potential application in biomedical devices, prostheses or structures for tissue engineering. According to activation energy results, obtained by Kissinger and Ozawa methods, the calcium phosphate used hinder the crystallization, probably due the viscosity increase and favors the bioactivity of the composite produced. The Ozawa-Avrami method used was adequate to represent the polyethylene/calcium phosphate behaviour, because the correlation coefficient was close to one.
