Abstract: | Abstract 2-Hydroxy-4-acryloxyacetophenone (HAAP) was synthesized and polymerized in 2-butanone using benzoyl peroxide as initiator at 65 °CC. Poly(2-hydroxy-4-acryloxyacetophenone-semicarbazone) (HAAPS) was prepared from poly(HAAP) and semicarbazide hydrochloride and was characterized by IR and NMR spectral studies. The molecular weights of the polymer was determined by gel permeation chromatography. Cu(II) and Ni(II) chelates of poly(HAAPS) were synthesized. Thermogravimetric analysis of the polychelates have been carried out. Elemental analysis of the poly chelates suggest a metal to ligand ratio as 1:2. The polychelates were also characterized by infrared, electronic spectral studies, magnetic, and conductivity measurements. |
