“…Under similar reaction conditions, FN copolymers showed a highest content of DIPF into the macrostructure, which indicates a greater reactivity of the propagating macroradical toward this comonomer. These results agree to the previously observed for other copolymerization reactions between dialkyl fumarates and acrylic or methacrylic monomers …”

“…On the other hand, dialkyl fumarates show low reactivity toward electron‐accepting monomers, such as acrylates, methacrylates, or acrylonitrile. Despite their low reactivity, some DRF‐metha/acrylate copolymers have been synthesized not only to clarify the monomer structure reactivity and the polymer structure–property relationship of these monomers but also for the potential applications that derive from them …”

This article presents the preparation of matrices from two new families of fumaric copolymers and the effect of structural differences on their physicochemical and biological behavior. Diisopropyl fumarate (DIPF) and poly(ethylene glycol) methyl ether methacrylate (OEGMA) or N-isopropylacrylamide (NIPAM) were copolymerized by conventional radical and RAFT polymerization to obtain lineal or start architectures, respectively. These copolymers were characterized by spectroscopic (FTIR and 1 H-NMR) and chromatographic methods. The thermal stability was studied by thermal gravimetric analysis, showing some differences in relation to the architecture and chemical nature of copolymers. SEM morphological analysis demonstrated that the surface of the matrices derived from OEGMA exhibited an irregular and rough surface, while DIPF-NIPAM copolymers presented smooth surface with nearly no significant porosity. The matrix obtained of both kinds of copolymers presented no cytotoxicity as it was evaluated using a model of macrophages on culture. Moreover, cell growth was better on the surfaces of the DIPF-NIPAM matrices, suggesting a good interaction with this matrix and its potential application as matrices for tissue engineering.

“…Similar degradation mechanisms were proposed for some copolymers of fumarate esters. Copolymers of di-n-docosyl fumarate (DnDF) with vinyl acetate and n-alkyl (meth)acrylates exhibited a single step degradation mechanism between 220 and 400 • C [47]. On the other hand, the thermal behavior of NBA and DIPF copolymers with different comonomer composition was studied by SEC and gas chromatographymass spectrometry (GC-MS) [26].…”

“…Poly(dialkyl maleate)‐based materials have found many applications such as pour point depressants/flow improvers, viscosity index improvers and additives in oil‐based products . Copolymerization of dialkyl maleates and fumarates with VAc via a free radical mechanism has been reported in the literature . Recently, it has been reported that dibutyl maleate (DBM)/VAc copolymers can be highly soluble in supercritical carbon dioxide (ScCO 2 ) fluid .…”

Iodine transfer radical homo-and copolymerization of vinyl acetate (VAc) with dibutyl maleate (DBM) were carried out in the presence of ethyl iodoacetate (EtIAc) and 2,2 -azobis(isobutyronitrile) (AIBN) as chain transfer agent and initiator, respectively, at 60 • C. Molecular weight and its distribution and (co)polymer structure (i.e. copolymer composition and chain end groups) were analysed using gel permeation chromatography and 1 H NMR spectroscopy, respectively. Homo-and copolymerization reactions proceed via a controlled characteristic with predetermined molecular weight and relatively narrow molecular weight distribution. The presence of DBM in the reaction mixture decreases the consumption rate of EtIAc as well as the polymerization rate. This is attributed to the effect of DBM on the transfer constant to the EtIAc and probably on the iodine exchange rate constant between the growing chains. The effect of the concentration of AIBN, EtIAc and overall monomers on the conversion, molecular weight and its distribution was studied. Simultaneously high conversion and molecular weight with a relatively narrow molecular weight distribution can be achieved only when equimolar and intermediate concentration of EtIAc and AIBN is used in the reaction mixture. End-group analysis by 1 H NMR reveals that iodinated VAc end groups in the (co)polymer chains are unstable, resulting in aldehyde end groups. Thermogravimetric analysis shows that the thermal stability of the VAc-based polymer increases on incorporating DBM units into the copolymer chains.
