Title:
POLYCARBONATE POLYOLS
Document Type and Number:
WIPO Patent Application WO/2020/121262
Kind Code:
A3
Abstract:
Embodiments of the present disclosure describe polymerization systems for the synthesis of polycarbonate polyols, methods of synthesizing polycarbonate polyols using the polymerization systems, methods of recovering initiators and/or activators for use or re-use in the synthesis of polycarbonate polyol, and the like. The polymerization systems can comprise an initiator including a mono- or multi-functional carboxylate or carbonate salt having an organic cation as a counter-ion; an optional co-initiator including a mono- or multi- functional protic compound selected from acids, alcohols, water, and combinations thereof; and an activator including a borane compound selected from alkyl boranes and aryl boranes; wherein the activator and one or more of the initiator and co-initiator associate to form an ate complex.
