Synthesis and Chemical Recycling of Polyurethane Materials Containing Acetal Linkages
Preserved Fulltext
This review concerns development of new chemically recyclable polyurethanes foams and elastomers. The key strategy is the introduction of acetal linkages into polyurethane backbones using acetal-containing polyols as raw materials. A treatment of these polyurethanes with aqueous acid at room temperature caused smooth hydrolysis reaction of the acetal linkages to produce polyols in high yield and high purity as degradation products.
