WeCAN® Cyclic Carbonate Monomers

We currently offer a suite of cyclic carbonate monomers and polyhydroxyurethane (PHU) vitrimers. The monomers use either petroleum-derived or biodegradable feedstocks along with carbon dioxide (CO₂) gas. This enables 100% atom-efficient conversion and storage of CO₂ into useful monomers for a variety of applications.

WeCAN® M101

3,4′-[(1-methylethylidene)bis(4,1-phenyleneoxymethylene)]bis[1,3-dioxolan-2-one]

CAS: 85023-51-4

Formula: C₂₃H₂₄O₈

Molecular Weight: 428.43 g/mol

Purity: >95%

Color: White or off-white powder

Melting Point: ~160°C

Synonyms: Bis(1′,3′-dioxolan-2′-on-4′-ylmethyl) bisphenol A ether; Bisphenol A diglycidyl ether (DGEBA or BADGE) biscarbonate; Bisphenol A diglycidyl ether di(cyclic carbonate) ester

WeCAN® M101 is a difunctional cyclic carbonate monomer designed for use in non-isocyanate polyurethane (NIPU) and polyhydroxyurethane (PHU) systems, including coatings, adhesives, and composites. Its rigid aromatic backbone enhances mechanical properties in the resulting cured materials.

WeCAN® M102

1,1,1-Tris[(2-oxo-1,3-dioxolan-4-yl)methoxy]methylpropane

CAS: 147876-32-2

Formula: C₁₈H₂₆O₁₂

Molecular Weight: 434.39 g/mol

Purity: Technical Grade
