| Popis: | The influence of freezing on reaction systems consisting of a polymer and suitable cross-linking agent in organic media has been studied. It was shown that the cryostructurization in organic medium displays mainly the same regularities as the processes of gelation at the freezing of aqueous polymer solutions in the presence of cross-agent. The study of two reaction systems was carried out: A — alternative N-viniylpyrrolidone — maleic anhydride and 4,4′-diaminodiphenyloxide in dimethylsulphoxide; B — polystyrene and p-xylylene dichloride in the presence of SnCl4 in nitrobenzene medium. |
