Abstract
o In the present work, synthesis and polymerization 3-amino-2-(l-.
(napthalen-2-yloxy)-3-oxo-3-phenylpropyl) quinazolin-4(3H)-one)-4
with mehtacrylic acid in the presence of N,N-dicyclohexyl
carbodimide (DCCI) as hydrating agent at 0°C and the prepared
monomers were polymerized in presence of lmol%
Azobisisobutyronitrile (AIBN) and dimethylformamide (DMF)as
solvent at 70CC.
o Copolymerization reactions between the monomer 7 with methyl
acrylate (MA), methylmethacrylate (MMA) and styrene (ST), the
composition of the resulting copolymers were calculated by knowing
the nitrogen content in the prepared copolymers using the elemental
analysis. The reactivity ratios of three systems studied were
determined by both Finemaun-Ross and Kelen-Tudos methods.
0 In all system studied no azeotropic copolymers appears and the
structure of all the synthesized compounds were confirmed by their
spectral and analytical data; IR and 1HNMR.
o Some of the newly synthesized compounds were screened for their
antimicrobial activity using the diffusion agar techniques were tested
against bacterial and fungal species which useful in pharma cological
species.
