Title:
DEGRADABLE POLYURETHANES CONTAINING SILYL ETHER LINKERS
Document Type and Number:
WIPO Patent Application WO/2024/044651
Kind Code:
A3
Abstract:
The present disclosure provides polymers comprising nl2 instances of a moiety of Formula (I): or a salt thereof. The present disclosure also provides methods of preparing the polymers and methods of degrading the polymers. Contacting the polymers with a fluoride nucleophile (e.g., tetrabutylammonium fluoride) or acid (e.g. octanoic acid) may degrade the polymers by cleaving the O-Si bonds. The polymers may be useful as degradable polymers, adhesives, coatings, elastomers, sealants, flexible foams, or structural materials.
