An improved manufacturing process was developed for the epoxy substituted mesogen 1 useful for the preparation of liquid crystalline materials. Notable features were telescoping of reactions, replacement of DCC with CDI for formation of a sensitive diaryl ester, and epoxidation using mCPBA in toluene. The process was validated on 100 kg scale.

The present invention brings about an increase in the thermal conductivity of an elastomer molded article over a preexisting value. The method according to the present invention is a method that uses at least one of a liquid crystalline polymer and a precursor therefor as a thermal conductivity modifier for an elastomer. That is, the thermal conductivity modifier for an elastomer according to the present invention contains at least one of a liquid crystalline polymer and a precursor therefor. The thermal conductivity modifier may contain only at least one of a liquid crystalline polymer and a precursor therefor or may contain at least one of a liquid crystalline polymer and a precursor therefor along with an additional component. The method and thermal conductivity modifier according to the present invention can bring about an increase in the thermal conductivity of an elastomer molded article over a preexisting value.

Low molecular weight tri-podal biphenyl- and benzoate-type mesogens [C6H5C6H4O(CH2)(5)SiMe2CH2CH2SiMe2](3)CH (4), [C11H23O(C6H4)(2)O(CH2)(5)SiMe2](3)CH (5) and [MeOC6H4OC(O)C6H4O(CH2)(5)SiMe2](3)CH (6) (C6H4 = 1,4-phenylene) were obtained, from branched silyl substituted methane precursors [CH2=CH(Me)(2)Si33CH (1) and (HMe2Si)(3)CH (2). The biphenyl-containing ones (4) and (5) were converted into terminal alkenes, which were subsequently hydrosilylated with poly(methylsiloxanes). The polymer derived from (5) exhibited mesomorphic properties. Such systems have the potential to significantly increase the density of liquid crystal rod-like structures in side chains of linear polymers (or dendritic liquid crystal polymers).
