Abstract
A process for recycling a polyurethane material wherein the polyurethane material comprises a moiety that is capable of undergoing decomposition through acidolysis, the process comprising: contacting the polyurethane material with an acid solution and allowing at least a portion of the polyurethane material to decompose into a recovered raw material composition comprising a degradation compound; and introducing an acetoacetylated polyol into the recovered raw material composition and reacting the acetoacetylated polyol with the degradation compound to form a polyol compound.
Claims19
A process for recycling a polyurethane material wherein the polyurethane material comprises a moiety that is capable of undergoing decomposition through acidolysis, the process comprising:
- contacting the polyurethane material with an acid solution and allowing at least a portion of the polyurethane material to decompose into a recovered raw material composition comprising a degradation compound (“Component (i)”), wherein Component (i) is an aldehyde compound, a ketone compound, or combinations thereof;
- and
- introducing an acetoacetylated polyol into the recovered raw material composition and reacting the acetoacetylated polyol and Component (i) to form a polyol compound (“Component (zz)”).
