摘要:
A method and apparatus (10) for detection of the degree of cure of a polymer in situ and non-invasively. The method and apparatus uses a solvatochromic probe molecule which upon curing produces a shift in the fluorescence emission spectrum as compared to a liquid polymerizable composition. The method and apparatus is particularly adapted for poly(vinyl) polymers. Preferred solvatochromic probe molecules are oxazones and pyrene.

摘要:
The present invention provides novel organic copolymers comprising alternating functional groups, wherein one functional group is phosphonate. In one embodiment, the copolymers comprise alternating phosphonate and N-substituted succinimide functional groups. In another embodiment, the copolymers are synthesized from maleimide and vinyl ether monomers, wherein the vinyl ether monomer possesses a pendant phosphonate functionality and the maleimide monomer is an N-substituted maleimide. Methods of synthesizing thin films with the novel organic copolymers, as well as chemical precipitation methods using the novel organic copolymers, are also provided.
