“…The onset degradation temperature for PDIPF and POEGMA, to be 250°C and 210°C, respectively . The first step of decomposition could be ascribed to the PEG's side chains lost, as it was observed for other structurally related copolymers . The last major decomposition step with a higher experimental loss of mass, at a maximum temperature value of 373°C for linear polymers (FO L ) and 338°C for branched polymers (FO S ), could be attributed to the random main chain scission.…”

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.

“…In the vast majority of studies regarding the manipulation of the LCST through copolymerization, two monomers known to produce homopolymers with LCSTs are copolymerized to produce statistical copolymers possessing intermediate LCSTs (Figure ). Luzon, Ramírez-Jiménez, Porsch, Bebis, and Lutz have all reported thermoresponsive copolymers based on OEGMA and DEGMA, where T CP decreased as a linear function of the molar quantity of DEGMA. ,− While numerous studies have been carried out involving the copolymerization of these two monomers, no consensus has been reached regarding the mechanisms underlying the capability to tune the LCST through copolymerization. Compared with their homopolymers, copolymers of the same degree of polymerization (DP) containing two or more thermoresponsive monomers can have different MW, hydrophobicity, surface area, radius of gyration, and so on.…”

Grafting Density Governs the Thermoresponsive Behavior of P(OEGMA-co-RMA) Statistical Copolymers

Thermoresponsive copolymers that exhibit a lower critical solution temperature (LCST) have been exploited to prepare stimuli-responsive materials for a broad range of applications. It is well understood that the LCST of such copolymers can be controlled by tuning molecular weight or through copolymerization of two known thermoresponsive monomers. However, no general methodology has been established to relate polymer properties to their temperature response in solution. Herein, we sought to develop a predictive relationship between polymer hydrophobicity and cloud point temperature ( T CP ). A series of statistical copolymers were synthesized based on hydrophilic oligoethylene glycol monomethyl ether methacrylate (OEGMA) and hydrophobic alkyl methacrylate monomers and their hydrophobicity was compared using surface area-normalized partition coefficients (log P oct /SA). However, while some insight was gained by comparing T CP and hydrophobicity values, further statistical analysis on both experimental and literature data showed that the molar percentage of comonomer (i.e., grafting density) was the strongest influencer of T CP , regardless of the comonomer used. The lack of dependence of T CP on comonomer chemistry implies that a broad range of functional, thermoresponsive materials can be prepared based on OEGMA by simply tuning grafting density.
