The Modification of Secondary High-Molecular Weight Guayule Rubber with Metachloroperoxybenzoic Acid
Polymers and High Performance Materials
The epoxidation of secondary high molecular weight guayule rubber has been accomplished. The reaction is performed using metachloroperoxybenzoic acid as the epoxidation agent in various stoichiometric ratios including 5, 10, 20, and 50 mol %. The products were characterized by infrared spectroscopy, H-1-and C-13-nuclear magnetic resonance (NMR), differential scanning calorimetry, and elemental analysis. H-1-NMR is used quantitatively to calculate epoxidation levels that are compared to stoichiometry. DSC results record a linear relationship between percent epoxidation and T(g).
