    • 2O (2 mL) and was subjected to analytical GC and subjected to GC-MS analysis. After filtration, the molecular weight of the pristine polymer samples was measured by gel permeation chromatography (GPC) on a Waters 2690 separations module apparatus and a Waters 2487 dual λ absorbance detector with chloroform as the eluent (flow rate 1.0 mL/min, 35°C, λ = 254 nm) with a series of three Styragel columns (104, 500, 100 Å; Polymer Standard Services). Toluene was used as an internal standard, and calibration based on polystyrene standards was applied for determination of molecular weights. GC-MS was performed on an Agilent 6890-5973 GC-MS workstation. The GC column was a Hewlett-Packard fused silica capillary column cross-linked with 5% phenyl-methyl siloxane. Helium was the carrier gas (1 mL/min). Unless otherwise noted, the following conditions were used for all GC/MS analyses: injector temperature, 250°C; initial temperature, 70°C; temperature ramp, 10°C/min; final temperature, 300°C.
