Cyclohexyl acrylate

A typical loss maximum of this type was observed for poly(methyl methacrylate) containing caprolactam or derivatives of cyclohexane12,13. It is noteworthy70 that in the latter case the relaxation induced by the cyclohexyl group present in the incorporated plasticizer and the secondary relaxation of poly(cyclohexyl methacrylate) or poly(cyclohexyl acrylate) are characterized by an identical temperature position, 190 K (1 Hz), and activation energy, 47.9 kJ/mol (AU = 47.7 kJ/mol is reported for the chair-chair transition of cydohexanol). Hence, it can be seen that the cyclohexyl ring inversion, which represents a specific molecular motion, is remarkably insensitive to the surrounding molecules. 

The membrane emulsification technique is also employed for the preparation of microspheres starting from monomers such as methacrylates (methylmethacrylate, cyclohexyl acrylate, etc.), polyimide prepolymer, styrene monomer [81], and so on.

Often, it is desirable to do patterning at lower temperature for higher throughput and reducing the thermal expansion mismatch. From the above analysis, one can use materials that have a lower Tg as NIL resist. In Fig. 4A, the imprinted patterns in poly(benzyl methacrylate) (M 70,000, Tg = 54°C) at temperature of 134°C are shown and in Fig. 4B, the patterns imprinted in poly(cyclohexyl acrylate) (M 150,000 Tg = 19°C) at 99° C are shown. In both cases, the imprinting temperatures were chosen to be Tg + 80° C °C and the applied pressure was 50 kg/cm, and very good pattern definition was obtained.

The catalyst was easily recovered, washed with diethyl ether and reused live times in the model reaction of oxophorone (148, R = H) with cyclohexyl acrylate, giving the corresponding product with unchanged high yield (75-94%).

Pd-complexes have also been impregnated on an amorphous silica support vnth the aid of a solution containing [BM IMjlPFej dissolved in tetrahydrofuran and these systems were applied as highly efficient catalysts for promoting Mizoroki-Heck coupling reactions between various aryl halides and cyclohexyl acrylate in alkanes without the presence of additional ligand (Scheme 5.6-8) [105].
