Synthesis and Characterization of Pendent Hydroxy Fluoroesters of Secondary High Molecular Weight Guayule Rubber
Polymers and High Performance Materials
The epoxidation of secondary high molecular weight guayule rubber (SHMWGR) and subsequent ring opening with fluoroacids to give hydroxyfluoroesters (FGR) is reported. Structural characterization was performed with FTIR; H-1-, C-13-, and F-19-NMR; and DSC. The percent epoxidation was quantitatively determined by H-1-NMR. it was noted that the glass transition temperatures (T-g) of the FGR polymers increased with increasing fluoro acid content; however, reactions with longer chain, highly fluorinated acids lowered the T-g.
