- Abstract
- Some bisphenol-A copolyformals, contg. in the main chain different amts. of a Ni-diimine nonlinear optical (NLO)-chromophore, eicosane and/or 2-butene units, were synthesized by condensation reaction between dibromomethane and suitable mixts. of Ni(II)/Schiff base complex, 1,20-di(bisphenol-A)ether-eicosane and/or 1,4-di(bisphenol-A)ether-2-butene. Structural compn. and thermal properties of polymeric materials were inferred by analyses by matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOFMS), NMR (NMR), gel permeation chromatog. (GPC), differential scanning calorimetry (DSC) and thermogravimetry (TG). MALDI-TOF data show that both Ni-diimine and unsatd. units are present in the copolyformals with a homogeneous arrangement in all the polymer mass range (GPC data). It has also been ascertained that the glass transition temp. (Tg) of the copolymers changes as a consequence of the abundance of aliph. units in the macromols. (DSC data). Crosslinking expts. of the copolymer at temps. near the Tg value and under UV irradn. were also performed. (literal)
