“…The temperature of the phase transition T pt of the PMPS network is larger than that of the poly(dimethylsiloxane) network (about Ϫ60 or Ϫ35°C). 12,21 Furthermore, the values of T pt for PMPS networks in IPNs (ϳ 63°C) are not greatly changed by the presence of the PMMA networks, and they are above those values in PDMS-PMMA IPN (Ϫ65°C). 12 On the other hand, the breadths of the T pt transition of IPNs (Fig.…”

“…The first synthesis of poly(dimethylsiloxane)-poly(methyl methacrylate) interpenetrating polymer networks was made by Sperling and Sarge. 4 Widmaier et al 11,12 further prepared the full IPNs based on poly(dimethylsiloxane) and PMMA by an in situ sequential synthesis. The authors performed tests for efficiency of catalyst, stress-strain behavior, hardness, surface properties, and the permeability to oxygen on the PDMS-PMMA IPNs.…”

“…Therefore, IPNs containing PDMS as a component were synthesized and their properties have been investigated extensively [17][18][19][20]. He et al [17] obtained PDMS-poly(methyl methacrylate) (PMMA) IPNs by an in situ sequential synthesis and examined the properties of the resulting IPNs. They reported that interpenetrating the PMMA networks in the PDMS networks can improve the poor mechanical properties of the PDMS membranes.…”

This paper focuses on the effects of the PSt content of polystyrene (PSt)-poly (dimethylsiloxane) (PDMS) interpenetrating network (IPN) polymer membranes on the pervaporation (PV) characteristics during the removal of benzene from an aqueous solution of dilute benzene. When an aqueous solution of 0.05wt% benzene was permeated through the PSt-PDMS IPN membranes, they showed high benzene/water selectivity. Both the permeability and the benzene/water selectivity of the membranes were enhanced with increasing PSt content in the PSt-PDMS IPN membrane. The physicochemical mechanism of permeation and separation through the PSt-PDMS IPN membranes during PV is also discussed. The best normalized permeation rate, separation factor for benzene selectivity, and PV separation index of the

“…Hence, reinforcement becomes necessary for many applications. 2 The conventional approach for reinforcement is to blend a particulate filler into PDMS before the matrix is cured into a network. A specific and very important example is the introduction of silica aerogel into PDMS.…”

␣,-Dihydroxy-polydimethylsiloxane (PDMS)/ poly(methyl methacrylate) (PMMA) blends were prepared by the radical polymerization of methyl methacrylate in the presence of PDMS, with benzoyl peroxide as the initiator. The PDMS/PMMA blends obtained by this method were a series of stable, white gums, which were vulcanized into elastomers at room temperature with methyl triethoxysilicane (MTES). The MTES dosage was much larger than the amount necessary for end-linking the hydroxy-terminated chains of PDMS, with the excess being hydrolyzed into crosslinked networks, which were similar to SiO 2 and acted as fillers. Investigations were carried out on the elastomeric materials by extraction measurements, swelling measurements, and scanning electron microscopy. The extraction data showed that at each composition, the sol fraction was less than expected. The extracted materials were further studied with swelling measurements, which revealed that the material obtained from an elastomer with a higher PMMA content had an apparently larger equilibrium swelling degree. Scanning electron microscopy demonstrated that the elastomer system had a microphase-separated structure consisting of PMMA domains within a continuous PDMS matrix. Moreover, the mechanical properties of the elastomeric materials were studied in detail.
