1PHBV Crystallization under Injection Molding Conditions:Influence of Packing Pressure and Mold Temperature显示文摘Poly(3-hydroxy butyrate)-co-(3-hydroxy valerate)(PHBV)is a biobased and biodegradable polyester.This semicrystalline bioplastic could be a good candidate for the replacement of some commodity plastics derived from oil.However,the control of the conditions of its processing in order to obtain optimal properties of the finished products remains a current research subject.The objective of this work is to better understand the crystallization under injection molding conditions by inline measurements during the process.We focused on the influence of two key processing parameters,namely,mold temperature and packing pressure.The modeling of inline temperature measurements allowed an inverse estimation of the thermodynamic melting temperature of PHBV and of the heat of crystallization’s variations with processing parameters.G.El hajj Sleiman G.Colomines R.Deterre I.Petit E.Leroy S.Belhabib 2018Journal of Renewable Materials2018,6,3:1
2Natural Rubber-Based Ionogels显示文摘Natural rubber(NR),besides being an abundant renewable resource for the elastomer industry,can be a potential resource for the design of innovative biobased polymer networks.The present work is based on“telechelic”liquid natural rubber oligomers obtained by controlled chemical degradation of NR.The chain ends of such oligomers can then be functionalized(with acrylate functions in the present case)and reacted with multifunctional crosslinkers in order to form networks.What’s more,the initial solubility of such thermosetting system in an ionic liquid(IL)can be used for the formulation of ionogels.Such solid networks typically containing 80%of IL were produced,resulting in high ionic conductivity performances.The oligomer chain length was shown to affect IL fragility due to confinement and specific interactions of ions with the host polymer network.TK.N.Tran A.Guyomard-Lack C.Cerclier B.Humbert G.Colomines J-F.Pilard R.Deterre J.Le Bideau E.Leroy 2018Journal of Renewable Materials2018,6,3:0
