Abstract
A method for formation of a polymer film in-situ according to the invention comprises steps of: providing a polymerizable composition in one or multiple parts; initiating polymerization of the polymerizable composition to form a polymerizing composition; prior to completion of polymerization of the polymerizable composition, forming a film therefrom; and fully polymerizing the polymerizing composition to form the polymer film.
Claims27
A continuous method for formation of a polymer film in-situ, the method comprising steps of:
- continuously providing a polymerizable composition in one or multiple parts;
- continuously initiating polymerization of the continuously provided polymerizable composition to form a polymerizing composition, wherein polymerization is initiated without use of external energy sources;
- prior to completion of polymerization of the polymerizing composition, forming a film therefrom on a supporting substrate;
- fully polymerizing the polymerizing composition using step-growth polymerization to form the polymer film on the supporting substrate, and
- continuously rolling the formed polymer film and the supporting substrate onto itself,
- wherein the polymer film is a continuous, single layer of material,
- wherein the polymer film can be physically separated from the supporting substrate on which the polymer film is formed.
