“…6. In case of CPMMA and CPMAN, the composition of BCPM in the chain of co-polymer, gradually increased with increased BCPM feed content, such behaviour was also observed in co-polymerization of MMA with N -phenylmaleimide [4], N -cyclohexylmaleimide [17] and N -(4-carboxyphenyl)maleimide [37]. In case of CPMST, the curve in Fig.…”

“…Considering all these aspects we have initiated studies on the synthesis and characterization of polymers and co-polymers of substituted-phenyl maleimide and reported co-polymerization of MMA and ST with CPMI [37]. We have also investigated [38,39] co-polymerization of MMA, ethyl acrylate and butyl acrylate with N -[4-N -(phenylamino-carbonyl)phenyl] maleimide initiated by AIBN in THF as was considered important to examine the changes in properties of copolymers through the modification of the carboxylic acid group by amidification.…”

Abstract-Co-polymers were synthesized from free radical co-polymerization of methyl methacrylate (MMA), styrene (ST) and acrylonitrile (AN) with N -(4-butoxycarbonylphenyl)maleimide (BCPM), using benzyl peroxide (BPO) as an initiator and DMF as a solvent at 85 • C. A series of co-polymers of MMA, ST and AN with BCPM was prepared using different feed ratio of comonomers. The thermo-stabilities and physical properties of the polymer samples obtained have been described. The values of monomer reactivity ratios r 1 and r 2 determined by Fineman-Ross and Kelen-Tudos methods are 0.28 and 0.90 in BCPM/MMA, 0.20 and 0.39 in BCPM/ST and 0.51 and 1.23 in BCPM/AN systems. Alfrey-Price Q and e values for BCPM are Q = 1.39 and e = 1.57 in BCPM/MMA, Q = 2.53 and e = 2.15 in BCPM/ST and Q = 1.11 and e = 1.89 in BCPM/AN systems.

“…found that the addition of N‐substituted maleimide (N‐cyclohexylmaleimide) increased the glass‐transition temperature ( T g ) and thermal stabilities of the copolymers. In addition, Oswal et al . synthesized a N‐(4‐carboxyphenyl) maleimide (CPMI)/methyl methacrylate (MMA) copolymer and CPMI homopolymer and found CPMI enhanced the initial decomposition temperature of the polymers, which they attributed to the thermal stability of the blends being improved by the five‐element ring .…”

P(N-phenylmaleimide-alt-styrene) (PNS) was synthesized, and nylon 6 (PA6)/PNS blends were prepared by melt blending. The heat resistant and crystallographic properties of PA6/PNS blends with different contents were investigated and analyzed. The results showed that the heat deflection temperature (HDT), relative crystallinity (X n ), and dynamic viscosity (η) increased with increasing PNS. The results of differential scanning calorimetry proved that PNS had played a positive role in nucleating PA6. Scanning electron microscosopy showed that the PNS domains were between 0.2 and 4 μm in diameter. The experimental results indicated that the addition of PNS improved the rigidity of PA6/PNS blends, thereby improving the heat-resistant properties of these blends.

“…M. Yuksel and his co-works [10] found that the glass transition temperature and thermal stabilities of the copolymers were increased by increasing the N-substituted maleimide (N-cyclohexylmaleimide) content. Last but not the least, Shantilal Oswal and his co-works [11] have synthesized CPMI/ MMA copolymer and CPMI homopolymer, and found CPMI enhanced the initial decomposition temperature of the copolymers. This is because the incorporated five member plannar cyclic structure in the chain of copolymer enhances the thermal stability of copolymer.4 The above literature shows that N-phenyl maleimide and its copolymers have played a positive role in improving the thermal stability and thermal stability of polymers.…”

In this work, nylon 6/ P(N-phenylmaleimide-alt-styrene) blends were prepared by melt blending, and the mechanical, heat-resistant, crystallographic and dynamical mechanical properties of nylon 6/ P(N-phenylmaleimide-alt-styrene) blends with different contents were investigated and analyzed. The results showed that the mechanical properties decreased with increasing PNS, while the heat deflection temperature (HDT), relative crystallinity (Xn), and storage modulus (G') increased with increasing PNS. The results of differential Scanning Calorimetry (DSC) proved the PNS played the positive role of nucleating PA6. And the results of dynamic mechanical analysis (DMA) proved the PNS could improve the rigidity of PA6/PNS blends. From the SEM, these PNS domains were between 0.2 and 4 μm in diameter. The experimental results indicated that the addition of PNS improved the rigidity of PA6/PNS blends, and then improved the heat-resistant property.
