In like manner a thickened, moldable intermediate is produced when appropriate amounts, as described herein, of 5-chloro-1-hexene, methylmaleic anhydride, a 1,2-epoxy octadecane, a 4:1 styrene-maleic anhydride copolymer and pyridine are heated to about 45° C. in the presence of t-butyl peroxypivalate. Also a thickened, moldable intermediate is produced when appropriate amounts of 1-octadecene, styrene, chloromaleic anhydride, 2,3 -epoxy-2-phenylhexane, a 1-hexene-maleic anhydride copolymer and N-methylpiperazine are heated to about 45° C. in the presence of 2-t-butylazo-2-cyano-4-methoxy-4-methylpentane.
