Whitcombe et al. observed a strong decrease of the cholesterol concentration, and hence excellent binding for cholesterol with p(EGDMA-co-CVPC) shell/ pMMA core particles in isohexane. When the carbonate ester was not hydrolyzed and hence no imprinted sites existed in the shell, only 2.7 pmol cholesterol per g particles were bound corresponding to the non-specifically adsorbed templates. Slightly less cholesterol was adsorbed to particles prepared without CVPC at all thus formed with a pure pEGDMA shell (<2 pmol g-1).

In 1959, Miller (1959a,fc) reported that radiation polymerization of a plasticized PVC containing a divinyl monomer could be used to crosslink PVC effectively without seriously affecting thermal stability. Three monomers were used poly(ethylene glycol dimethacrylate) (PEGDMA), ethylene glycol... 

Watanabe and coworkers [5, 454, 455] studied the DMFC performance of sPI and crosslinked sPI membranes obtained by polycondensation of NTDA, bis (3-sulfo propoxy)benzidine (BSPB), and alkaline diamine [5]. Other studies on polyimide membranes focused on methanol selectivity [456], DMFC performance [457], and the effect of crosslinking on the methanol selectivity [458]. Hybrid sPI membranes were prepared, including composites with PAMPS [459], PTA [460], Nafion infiltrated sPI membranes [461], sPI membranes coated with crosslinkable poly(ethylene glycol) dimethylacrilate (PEGDMA) [462], and mesoporous silica [463, 464],... 

All the sPI composite membranes are located in flie A quadrant, that is have higher proton conductivities and lower methanol permeability than Nafion. The sPl composite with PTA [460] has a poor DMFC performance, but sPBl layered with PEGDMA reached MPD of 120 mW.cm at 60 °C [462]. The behavior of the sPI/Nafion composite is exceptional, exhibiting =79 and a MPD of 130 mW. cm at 70 °C with 5 M methanol. 

PEGDMA-SSA membranes exhibit proton conductivities similar to Nafion and methanol permeabilities slightly lower than Nafion, leading to relative selectivities in the range 1.5-2.0, while PDEGDMA-SSA membranes have <1 [482]. HNBR/...

Commonly used chain formers are methacrylamide (MAM), hydroxymethacry-lamide (HMAM), N-vinyl pyrrolidone (NVP), and methoxy poly(ethylene glycol) monomethacrylate (MPEGMA). Sometimes two monomers may be used in combination (e.g., MAM and NVP, or MPEGMA and HMAM). The cross-linkers commonly used are methylene bisacrylamide (MBAM) and poly(ethylene glycol) dimethacrylate (PEGDMA). The free radical initiator used most often is ammonium persulfate (APS) with tetramethylethylene diamine (TEMED) used as a catalyst.
