| Abstract: | Interpenetrating polymer based on camphor
and poly(antimonyacrylate) using benzoylperoxide (BPO) as an initiator
and divinyl benzene as cross-linking agent have been synthesized. The formation
of IPN has been confirmed by presence of two-phase in SEM photographs. The IR spectrum
reveals a band at 1730 cm-1 due to –C=O group and at 3030 cm-1
due to aromatic C–C stretching of phenyl group. Specific rotation [ ]25
= + 43.2° is observed for IPN (whereas that of pure camphor is 43.5 ± 1). The
shifting of band from 1705 cm-1 to 1730 cm-1, due to
carbonyl group of camphor confirms the formation of complex between camphor and
poly(antimony acrylate). The value of mutual interaction constant (kAB) between polymer (A) and
camphor (B) in DMSO, DMF, dioxan are calculated as DMSO (kAB = 0.7), DMF (kAB
= 0.63) and dioxan (kAB =
0.22). The properties like percentage swelling, average molecular weight
between crosslinks (Mc),
Young’s modulus are generally direct function of [poly (antimonyacrylate)] and
[divinyl benzene]. The values of glass transition temperature (Tg) and activation energy (Ea) of IPN, calculated from
DSC and TGA, are 240°C and 25 kJ/mol, respectively. |
