Preparation of Organic Dye Gradients for Optical Limiters
Abstract
Isothermal Frontal Polymerization (IFP) is a polymerization method that propagates directionally as opposed to homogeneous polymerization. The propagation distances of Poly(Methyl Methacrylate)/Methyl Methacrylate systems can be increased by increasing the parameters of initiator decomposition rate, initiator concentration, and temperature and/or by adding a polymeric inhibitor to the bulk solution. IFP does not depend on the size of the polymeric seed, but a critical seed molecular weight must be maintained for maximum propagation. The current method of front detection is invasive and inadequate giving quantitatively irreproducible results, and thus, a new detection method is required.
