Chemical Modification of Plasticized Lignins Using Reactive Extrusion
Frontiers in Chemistry, 2019 The reaction of esterification of plasticized Kraft lignin (KL) with succinic and maleic anhydrides using reactive extrusion (REX) was studied in detail. DMSO, glycol and glycerol were found to be efficient plasticizers for lignin. The chemical structure

Advantages of polycarboxylic over dicarboxylic anhydrides in the melt modification of PPC
eXPRESS Polymer Letters, 2013 We present an alternative polymer modification of poly (propylene carbonate) (PPC). A conventional practice for PPC melt processing is the melt – modification with maleic anhydride (MAH) – a di-carboxylic anhydride –.
