## Abstract Gelation of the reaction mixture and insolubility of the poly(__p__‐phenylene vinylenes) (PPVs) when isolated at this stage, but complete redissolution of the gel and excellent solubility of the resulting PPVs after further stirring for hours or days, is a phenomenon in Gilch polymeriza
