Cryotropic gelation poly

All these favorable and unfavorable factors and mechanisms are effective to a different extent during cryotropic gelation in both aqueous and organic media. For instance. Fig. 15 shows the bell-like temperature dependence of the gel-fraction yield when poly(styrene) was crosslinked with 4,4 -xylylene dichloride in nitrobenzene (see Fig.Sa for the reaction scheme). At temperatures 30-40 °C lower than room temperature, the efficiency of polymer crossUnking is higher than in unfrozen solutions (curve with open circles in Fig. 15) [27]. Thus, close similarity in the character of such temperature dependences for the processes in frozen aqueous and... [Pg.81]
