Synthesis and characterizations of calcium di(meth)acrylate divinyl monomers and melt surface graft functionalization with linear low density poly(ethylene)

Abstract

AbstractCalcium diacrylate (CDA) and calcium dimethacrylate (CDM) divinyl monomers were synthesized by a solvo thermal method. The FTIR spectra showed a peak at 1650 cm−1 due to the presence of a CC for both CDA and CDM. Proton NMR and carbon NMR confirmed the structure of CDA and CDM synthesized by a solvo thermal method. DSC determined the melting temperatures of CDA and CDM. XRD indicated the presence of a d110 plane peak for CDA and CDM. The % weight residue that remained above 700°C in TGA method confirmed the higher thermal stability of CDA. Thus, synthesized CDA and CDM were surface grafted on linear low density poly(ethylene) (LLDPE) at 160°C under inert atmosphere by thermolysis method. FTIR confirmed the presence of CO stretching due to CDA and CDM in LLDPE backbone after thermolysis reaction. 1H‐NMR confirmed the chemical grafting of CDM onto LLDPE. © 2009 Wiley Periodicals, Inc.
