Abstract: The present invention is directed to an epoxy-containing polymeric material having nonlinear optical properties, particularly a glycidyl amine polymer, and a process for making the nonlinear optical (NLO) epoxy-containing polymeric material including poling the polymeric material under high voltage at elevated temperature for a period of time to bring about orientation of the nonlinear optical functionalities in the polymer. The polymers have enhanced thermal stability and good NLO properties.

Abstract: This invention provides novel polyoxyalkylene polymers which exhibit nonlinear optical response, and which have utility as a transparent optical component in electrooptic light modulator devices.

Abstract: The invention entitled "Polymers containing polyalkylpiperidines and use thereof as stabilizers" provides a class of polymers in which groups containing sterically hindered polyalkylpiperidines are linked in the main chain of the polymers via bridging members containing 2-hydroxy-1,3-trimethylene groups.The polymers show superior stabilizing effects for various synthetic polymers such as polyolefins against degradation thereof induced by light and/or heat. The polymers have advantages, as compared with known stabilizer compounds, that they hardly volatile upon processing with heating or during storage of articles containing thereof, and that they are resistant to extraction with solvents from articles containing thereof.

Abstract: Water-dispersible resins formed from polyglycidyl ethers of polyphenols and N-heterocyclic compounds and containing cationic salt groups are disclosed. The resins can be dispersed or dissolved in water, and can be applied to a wide variety of different substrates by electrodeposition, depositing on the cathode to provide superior corrosion-resistant coatings.
