“…9(a)-(c) shows the instantaneous and cumulative copolymer molar fraction and the average sequence length for the system MTm-AA as a function of the conversion and the feed molar fraction. The shown graphs have been obtained by using the algorithm 'Conversion' developed by Gallardo et al [23]. This algorithm has been proved useful to theoretically predict, from the knowing reactivity ratio values and without any approximation (except those considered by the terminal model), the course of any binary copolymerization reaction with the conversion.…”

“…As the reaction volume is the same, the MV system gives the tightest network. [7] where f E is the molar fraction of the crosslinker against the total amount of monomers (0.01 in this case); n M and n VP are the number of M and VP functionalities per crosslinker. n M =2 for MM, 1 for MV, 1 for MM+VV, 0 for VV.…”

Amphiphilic networks segregated in hydrophilic and hydrophobic domains are very attractive materials because they show unique properties related to the combination of both components. In this work, these types of networks have been obtained in a very simple way by single standard bulk radical photocopolymerization of vinylpyrrolidone, and n-butylmethacrylate, in the presence of 1 mol % of crosslinkers with different homology towards both components. The crosslinker homology (methacrylate or VP-like functionalities) has shown to have a strong influence on the sol content and on the different properties of the materials, such as segregation or the variation of the storage modulus with temperature and hydration. The experimental results are in good agreement with a theoretical prediction of the network formation carried out assuming that the reaction may be described compositionally by the terminal model. The most efficient crosslinking has been obtained using an asymmetric crosslinker bearing simultaneously methacrylate and VP-like groups.3

“…However, this penultimate model is very complex. Actually, when the model tries to describe a reaction compositionally it is usually reduced to the terminal one, which is the model used here to perform a basic theoretical description of the reaction using the software Copol [17,18].…”

A series of poly-(N-isopropyl acrylamide)-based copolymers were developed with a view to biomedical applications, specifically cell cultivation and recovery. Ethylpyrrolidone methacrylate (EPM), the monomer of poly-(ethylpyrrolidone methacrylate) (pEPM), which is itself thermoresponsive, was copolymerized with N-isopropylacrylamide in varying ratios to create this novel thermoresponsive copolymer series. Characterization indicated a moderate increase of copolymer lower critical solution temperature with increasing EPM content. Films of the copolymers successfully hosted cells to monolayer. Cells detached from the copolymers upon temperature reduction with cell to cell junctions maintained, avoiding the damage which can be caused using conventional detachment techniques. These results indicate that these copolymers are highly cell compatible and may be useful for a range of biomedical applications.
