Description

For the purpose of chemical recycling of waste windshield polyvinyl butyral (PVB) interlayers, novel PVB organogels were prepared by the gelation of PVB containing PVA units of ca. 20 mol% with pyromellitic dianhydride (PMDA) as crosslinker and phthalic (PAH) or trimellitic anhydrides (TAH) as a chemical modifier. The resulting PVB organogels had a high swelling degree in organic solvents such as N,N-dimethylformamide and methanol in the solubility parameter 12 to 15 region. The order of swelling degree was as follows: PVB organogel prepared with PMDA+TAH > that with PMDA+PAH > that with only PMDA. The swelling degree drastically increased with an increase of the amount of carboxy groups introduced in the organogels, because conversion of carboxy groups into carboxylate ions was promoted by triethylamine used as base-catalyst.
