“…The lower glass transition temperature for the former material might be explained by the smaller barrier of rotation for the protruding (trifluoromethoxy)ether group which has the effect of introducing chain flexibility and additional free volume . The T g of 2d (52 °C), higher than 2b (38 °C), is consistent with the trend detected when comparing the organic polymers polystyrene (105 °C) and poly(2,5‐bis(trifluoromethyl)styrene) (116 °C) . For 2e , no glass transition was observed below ≈135 °C, above which decomposition of the polymer occurred.…”

“…The calibration of the instrument was carried out using indium and zinc as calibration standards. Thermogravimetric analysis (5% weight loss) was performed on Hi‐Res Modulated TGA 2950 at a scan rate of 20 °C min −1 10. The molecular weights ( M n and M w ) of the polymers were determined by gel‐permeation chromatography (GPC) (Shimadzu) using THF as the eluent with a flow rate of 1 mL min −1 and differential refractometric detector (RID‐10A).…”

“…These polymers are thermally stable and the degradations temperatures (5% weight loss) were in the range of ≈350 °C and 390 °C for P2 and P1, respectively. These results are very much comparable to those of trifluoromethyl‐substituted polystyrenes 10. The polymers are amorphous and the T g of polymers P1 and P2 is summarized together with T g values for other substituted derivatives of polystyrenes (–CH 3 , –CF 3 , and –OCH 3 ) in Table 2.…”

“…The copolymerization of styrene with p ‐stearoyl styrene contributed to develop novel polymeric solid–solid phase change materials having considerable potential for thermal energy storage and temperature‐control applications . Teng et al synthesized thermally stable, flexible with high transmittance copolymers by the copolymerization of trifluoromethyl substituted styrene derivatives with methacrylate. These copolymers may be used as novel optical materials .…”
