Abstract
The present disclosure provides synthesizing multi-functional polymerizable compounds and methods for the synthesizing the same. The methods include reacting a compound of Formula (Ia) with an epoxide of Formula (Ib) with quantitative conversion, requiring only an aqueous work-up for purification. Further provided herein are methods of producing polymerizable composition, methods of forming an article by additive manufacturing processes (e.g., via 3D printing), such as orthodontic appliances with increased stain resistance.
Claims29
A compound having the structure of Formula (I) or a salt thereof:
- wherein:
