Polymeric derivatives of 4-alkyldithiocarboxylate-5-hydroxypyrazoles have been prepared by bulk vinylic homo and copolymerization of 4-allyldithiocarboxylate-5-hydroxy-3-methyl-l-phenylpyrazol.Brought to you by | Purdue University Libraries Authenticated Download Date | 6/8/15 2:57 PM Vol. 9, No. 4, 2003 Polyvinyls derivatives of 4-allyldithioo-carboxylate-5-hydroxy-3-methoxy-l phenylpyrazol When R 2 in the general structure I is an allylic substituent it is possible to carry out vinylic polimerization and in order to get chelating polymers containing the 4-alkyldithiocarboxylate-5-hydroxypyrazol moiety, we have studied the bulk homopolymerization of 4-allyldithiocarboxylate-5-hydroxy-3-methyl-l-phenylpyrazol 1 and the copolymerization with styrene or acrylamide.
