Polymethyi methacrylate

Table 6 Mechanical properties of polymethyi methacrylate-based self-reinforced polymer composites, as described in the literature...

Molecular weight and polydispersity were determined by gel permeation chromatography (GPC) analysis with a Waters GPC system (comprising a SIS HPLC pump, a 717 autosampler, a 2410 RI detector, a column heater and two Styragel HT6E coliunns), with a mobile phase of HFIP with 0.0 IM LiBr at the flow rate of O.S ml/min. The specimens were dissolved in hexafluoroisopropanol (HFIP) at a concentration of 2 mg/ml. The solution was filtered with a S ml polypropylene (PP) syringe equi ped with a 0.4S pm PP filter to remove any insoluble materials prior to GPC injection. Polymethyi methacrylate standards with narrow polydispersity were used for calibration. The data was analyzed by Millennium version 3.0S.01 software.
