Abstract
In this letter, we report high electro-optic methylene di(phenylene is ocyanate) (MDI)/DR19 side-chain polymer him polymerization by vapor de position polymerization. For samples deposited at substrate temperatur es from 10 to 30 degrees C, the electro-optic (EO) coefficient, r(33), was measured to be 5 pm/V after poling. A lifetime of about one week was obtained. The highest EO effect observed were films deposited at - 40 degrees C and polymerized after poling. The EO coefficient of these samples is about 24 pm/V while the lifetime is only about 30 min. The effect of substrate temperature, the ratio of monomers, and the polin g temperature on the nonlinearity of the films are studied. (C) 1996 A merican Institute of Physics.
