Abstract
A method of forming a polymer is disclosed. The method comprises: positioning a mould in relation to a bath containing a molten material to form a mould cavity between the mould and the molten material; adding a monomer within the mould cavity; and curing the monomer to form a polymer.
Claims22
A method of forming a polymer, comprising:
- positioning a mold in relation to a bath containing a molten material to form a mold cavity between the mold and a top surface of the molten material, wherein the molten material forms one wall of the mold cavity and forms a shaping surface for the cured monomer;
- adding a monomer within the mold cavity;
- curing the monomer to form a polymer;
- and
- solidifying at least part of the molten material after curing the monomer.
