摘要

<正>New Schiff base polymers poly[4,4’-methylenebis（cinnamaldehyde）ethylenediimine] （PMBCen）, poly[4,4’-methylenebis（cinnamaldehyde） 1,2-propylenediimine] （PMBCPn）, poly[4,4’-methylenebis（cinnamaldehyde） 1,3-propylenediimine] （PMBCPR）, poly[4,4’-methylenebis（cinnamaldehyde）l,2-phenylenediimine] （PMBCPh）, poly[4,4’-methylene-bis（cinnamaldehyde）meso-stilbenediimine] （PMBCS）, poly[4,4’-methylenebis（cinnamaldehyde）urea] （PMBCUR）, poly[4,4’-methylenebis（cinnamaldehyde）semicarbazone] （PMBCSc）, poly[4,4’-methylenebis（cinnamaldehyde）thiosemicarbazone] （PMBCTSc） and poly[4,4’-methylenebis（cinnamaldehyde）hydrazone] （PMBCH） were formed by polycondensation of 4,4’-methylenebis（cinnamaldehyde） with ethylenediamine, 1,2-propylenediamine, 1,3-propylenediamine, 1,2-phenylenediamine, meso-stilbenediamine, urea, semicarbazide, thiosemicarbazide and hydrazine, respectively. The dialdehyde and polymers have been characterized through elemental micro-analysis, IR, UV-Vis and ’H-NMR spectroscopic techniques. Thermoanalytical studies and viscous flow of dilute solutions of dialdehyde and its polymers have been examined and compared.
