This invention relates to methods for forming polymer(s) including heating of a polymer to be formed to a temperature above its glass transition temperature, continuously depositing (preferably by flowing or laying) the polymer onto a moulding surface (herein the “lower moulding surface”) of a first mould, (preferably in a manner that reduces, eliminates or minimises shear stress or other stress in the polymer so deposited), the polymer remaining above the glass transition temperature, applying a moulding surface (herein the “upper surface”) of the polymer while the polymer remains at a temperature above the glass transition temperature, and allowing the polymer to transition to below the glass transition temperature while within or between the upper and lower moulding surfaces, wherein the polymer is removed from the moulding surfaces. Apparatus is also provided.
