“…This feature can be related to a minimum hydroxyl group's density acting as charge carriers in the conducting process, distributed in the polymer network instead of being in the crystalline domains, when the PVA content in the HPN is low. These results are in agreement with Xie et al [20] studies on conductivity in semicrystalline polymers, which showed that the ionic conductivity decreases with the increase of poly (ethylene oxide) crystallinity reaching values around 10 À3 -10 À2 X À1 cm À1 . The ionic conductivity variation with the PVA/CHI ratio, whether the parent polymers are crosslinked with glutaraldehyde, can be related to hydroxyl groups and morphology Table 3 Fitting parameters used to simulate the EIS data for PVA/CHI blends (Fig.…”

“…Xie et al in 1994 20 synthesized simultaneous interpenetrating polymer network based on (castor oil-polyethylene glycol) polyurethane and poly(2-vinyl pyridine) (VP). They coupled castor oil and polyethylene glycol (PEG) with 2,4-toluene diisocyanate and vinyl pyridine by radical polymerization.…”

Non-biodegradable polymers are causing severe damage to the environment. To counter this, need of biodegradable polymers is gaining a rapid growth in numbers as well in their applications and quantities used. In addition, due to the oil crises worldwide, focuses from synthesizing polymers from petroleum has shifted to the synthesis of polymers from renewable resources such as vegetable oils. The advantage of vegetable oils is they are easily available, have multiple functional groups attached like the double bonds, hydroxyl groups and other functional groups, which provides ease of reactions and modification like epoxidation etc. The use of vegetable oils in the polymer renders biodegradability to the polymer. Different researchers have used different vegetables oils like castor oil, linseed oil, soybean oil, sunflower oil and canola oils for synthesis of polymers and utilized them in diverse fields like biomedical, coatings, adhesives, IPN's and as structural materials. This review discusses the synthesis, characterization, degradation and applications of polymers obtained from natural oils such as castor oil, soybean oil, linseed oil and some other oils.

“…In the last decades, a lot of works have been done to develop new materials for many different application using renewable resources. The castor oil has been used widely thanks to its chemical structure [1][2][3][4][5][6] . Castor oil is a naturally occurring monomer, which is a triglyceride of ricinoleic acid containing three hydroxyl groups and three double bonds.…”

In this work was employed a 2 3 factorial experiment design to evaluate the castor oil polyurethane-poly(methyl methacrylate) semi-IPN synthesis. The reaction parameters used as independent variables were NCO/OH molar ratio, polyurethane polymerization time and methyl methacrylate (MMA) content. The semi-IPNs were cured over 28 h using two thermal treatments. The polymers were characterized by infrared and Raman spectroscopy, thermal analysis and swelling profiles in n-hexane. The glass transition temperature (Tg) and the swelling were more affect by the NCO/OH molar ratio variation. The semi-IPNs showed Tg from -27 to -6 °C and the swelling range was from 3 to 22%, according to the crosslink density. The IPN mechanical properties were dependent on the cure temperature and MMA content in it. Lower elastic modulus values were observed in IPNs cured at room temperature.
