“…These results indicate that the thermal stability of IPN XNR/CSt samples was significantly improved corresponding with the increase in the cross-link density of XNR and the gel fraction of IPN XNR/CSt with increasing MBA content. Furthermore, this phenomenon is in good agreement with the previous works 29,30 stated that polymer with higher cross-link density needs the higher values of activation energy for the thermal decomposition. However, the increase in MBA content from 1.0 phr to 2.5 phr has no significant change in the TGA thermograms of IPN XNR/CSt samples.…”

A series of interpenetrating polymer network (IPN) hydrogels based on cross-linked natural rubber (XNR) and cassava starch (CSt) as biodegradable membrane material were synthesized via free radical polymerization in latex state using N, N′-methylene bisacrylamide (MBA) and maleic acid as cross-linkers. The IPN XNR/CSt hydrogels were confirmed and characterized by infrared spectroscopy, thermal analysis, and X-ray diffraction. The results showed that with increasing MBA content from 1.0 to 2.5 phr, cross-link density and gel fraction of XNR increased from 0.80 to 0.90 mol M−3 and from 19.7% to 30.5%, respectively. The gel fraction and tensile strength of the IPN XNR/CSt hydrogels also gradually increased as a function of MBA content but the water swelling and elongation at break decreased slightly. The IPN XNR/CSt containing 1.0 phr MBA displayed the highest water swelling of 82%. The weight retentions of IPN XNR/CSt hydrogels after soil degradations for 90 days increased from 48% to 56% with increasing MBA from 1.0 phr to 2.5 phr. The IPN XNR/CSt exhibited not only a good biodegradation but also high mechanical strength and flexibility. Also, the IPN XNR/CSt could be a promising candidate as a biodegradable membrane for longer released fertilizer application.

“…As it appears from Table 1, a significant increase of both Tg (from 73 C to 115 C) and storage modulus (from 2.5 GPa to 3.0 GPa) can be obtained by re-formulating the UV curable resin in the form of an IPN dual-cure system. In addition, one single Tg was observed in the IPN system, as a further demonstration of the excellent structural homogeneity of the materials [18]. High storage moduli were measured also for the CFR composites (3.8 GPa and 7.7 GPa for the CF5 and CF30 composite formulations, respectively).…”

“…The width of tan d peak can indicate sample homogeneity 18 ; the broader the tan d peak, the greater the nonhomogeneity of the sample. MC3 copolymer, with the highest MMA content, shows the broadest tan d peak which is characteristic of a low homogenous crosslinked network.…”

The macromer was synthesized using medium oil length oleic acid, phthalic anhydride, and glycerol. The synthesized macromer and methyl methacrylate (MMA) were copolymerized by free radical polymerization in toluene. The ratio between the macromer and MMA changed, and the effects on different properties of the copolymers, such as glass transition temperature (T g ) and film properties, were studied. The macromer and copolymer structures were characterized by FTIR and 1 H NMR spectroscopies. The coatings prepared with the highest ratio of MMA exhibited better overall physico-chemical properties. Alternatively, Tafel polarization curves showed that the corrosion rate value in NaCl solution decreases significantly when the MMA content is increased. Dynamic mechanical analysis results revealed that the increasing amounts of MMA lead to increasing T g values of copolymers.
