Abstract
The disclosure describes a polymerizable liquid that includes a reactive oligomer and a reactive monomer. The polymerizable liquid is an energy polymerizable liquid hardenable by a single reaction mechanism forming a Photoplastic material. The disclosure further describes a method of producing the Photoplastic material and articles that can be made from the Photoplastic material.

A one part free radical polymerizable liquid for forming a three dimensionally printed dental aligner, the free radical polymerizable liquid comprising:
- between 40 wt. % and 69 wt. % of a reactive multi-functional oligomer, the reactive multi-functional oligomer being at least one of (i) a multi-functional methacrylate oligomer, and (ii) a multi-functional acrylate oligomer;
- and
- between 30 wt. % and 59 wt. % of a reactive monofunctional monomer, the reactive monofunctional monomer being at least one of (i) a monofunctional N-vinyl monomer, (ii) a mono functional vinyl ether monomer, (iii) a monofunctional vinyl ester monomer, (iv) a mono functional vinylamide monomer, (v) a styrene monomer, (vi) a monofunctional (meth) acrylate monomer, (vii) a monofunctional vinyl carbonate monomer, and (viii) a monofunctional vinyl carbamate monomer,
- wherein a molar bond ratio of the at least one reactive ethylenically unsaturated group of the at least one reactive monofunctional monomer to the reactive ethylenically unsaturated groups of the at least one reactive multi-functional oligomer is at least 5:1, the free radical polymerizable liquid hardening by a single reaction mechanism to form a photoplastic three dimensionally printed dental aligner.
A method for forming a polymerizable liquid, the method comprising:
- mixing together:
- between 40 wt. % and 69 wt. % of a reactive oligomer, the reactive oligomer being at least one of (i) a 1 or more functional N-vinyl oligomer, (ii) a 1 or more functional vinyl ether oligomer, (iii) a 1 or more functional vinyl ester oligomer, (iv) a 1 or more functional vinylamide oligomer, (v) a styrene oligomer, (vi) a 1 or more functional (meth) acrylate oligomer, and (vii) a 1 or more functional vinyl carbonate oligomer;
- and
- between 30 wt. % and 59 wt. % of a reactive monomer, the reactive monomer being at least one of (i) a 1 or more functional N-vinyl monomer, (ii) a 1 or more functional vinyl ether monomer, (iii) a 1 or more functional vinyl ester monomer, (iv) a 1 or more functional vinylamide monomer, (v) a styrene monomer, (vi) a 1 or more functional (meth) acrylate monomer, and (vii) a 1 or more functional vinyl carbonate monomer,
- wherein a molar bond ratio of the at least one reactive ethylenically unsaturated group of the at least one reactive monomer to the at least one reactive ethylenically unsaturated group of the at least one reactive oligomer is at least 5:1, the polymerizable liquid being an energy polymerizable liquid hardenable by a single reaction mechanism to form a photoplastic three dimensionally printed dental aligner.
