Cc. Yang et al., SYNTHESIS OF CROSS-LINKED 2ND-ORDER NONLI NEAR-OPTICAL POLYMERS WITH HIGH T-G, Gaodeng xuexiao huaxue xuebao, 16(8), 1995, pp. 1315-1318
Synthesis and characterization of a diamino dihydroxyl azo compound we
re reported, The crosslinking reaction process of the diamino dihydrox
yl azo compound with the biuret of hexamethylene diisocyanate was stud
ied by FTIR, The glass transition temperatures of crosslinked polymers
were measured by DSC, The orientation and oriented stability of cross
linked and poled polymers were studied by UV-Vis spectra.
