Effect of thermo-oxidation on loss of plasticizers, on crystalline features and on properties in a metallocene isotactic polypropylene

Incorporation of a low content of several plasticizers into a metallocene isotactic polypropylene (iPP) has been performed in order to learn about their stability and performance by the action of a thermo-oxidative degradation treatment at 95 °C for different times. Comparison with the behavior exhi...

The synchrotron experiments were performed at beamline BL11-NCD at ALBA Synchrotron Light Facility with the collaboration of ALBA staff. Authors are grateful for the funding received to perform these measurements. Authors would like to thank to Dr. N. García her help in the measurements with the optical profilometer.Peer ReviewedElsevierMinisterio de Economía y Competitividad (España)European CommissionConsejo Superior de Investigaciones Científicas [https://ror.org/02gfc7t72]2019201920192019info:eu-repo/semantics/articlehttp://purl.org/coar/resource_type/c_6501http://hdl.handle.net/10261/194297reponame:DIGITAL.CSIC.
