Thermosensitive polymer structures based on segmented copolymer networks

Microphase separation under constraints: a molecular thermodynamic theory for polyelectrolytic amphiphilic model networks in water

“…A more recent biomedical application of CSACPNs is their use as scaffolds in tissue engineering [8]. Other applications include their use as organic solvent adsorbents [9], pervaporation membranes [10], templates for the preparation of silica particles [11], and temperature-responsive actuators [12].…”

Thermo-Responsive Solid-Phase Extraction Using Poly(methyl vinyl ether)-Containing Segmented Polymer Networks

“…A typical example is as follows. 0.15 g of styrene and 2.85 g of PMVE-dimethacrylate [3] (M n = 4 100 g/mol) were dissolved in 1 ml of toluene in a 10 ml flask. 32 mg of free-radical initiator Perkadoxm were added and the mixture was degassed four times.…”

“…In this work, segmented polymer networks, obtained by copolymerization of a macromolecular crosslinker with a second vinyl monomer, were evaluated as SPE materials. Poly(methyl vinyl ether)-a,x-dimethacrylate, prepared by end-capping living bifunctional poly-(methyl vinyl ether) (PMVE) with 2-hydroxyethyl methacrylate (HEMA), [3,4] was used as the macromolecular crosslinker. PMVE exhibits a lower critical solution tem-perature (LCST) behavior in water around 37 8C, [5] meaning the polymer is water-soluble below 37 8C and precipitates when the temperature is raised above 37 8C.…”

Functional segmented polymer networks based on polytetrahydrofuran and poly(vinylbenzyl chloride)

“…Segmented polymer networks, also referred to as block copolymer networks, are generally produced by copolymerisation of a monomer A with a bismacromonomer of monomer B, i.e., a polymer provided with two (co)polymerisable end groups [11][12][13]. Several examples of such segmented polymer networks have been described recently [14][15][16][17], some of which containing reactive functional groups such as tertiary amines [18], amino-dendrimers [19] or carboxylic acids [20].…”
