SIDE CHAIN LIQUID CRYSTAL EPOXY MONOMER (S-LCEM) AND PREPARATION METHOD THEREOF, AND SIDE CHAIN LIQUID CRYSTAL EPOXY RESIN (S-LCER) WITH HIGH INTRINSIC THERMAL CONDUCTIVITY
The present disclosure provides a side chain liquid crystal epoxy monomer (S-LCEM) and a preparation method thereof, and a side chain liquid crystal epoxy resin (S-LCER) with high intrinsic thermal conductivity, and belongs to the technical field of epoxy resin materials. There are biphenyl mesogenic groups with strong rigidity in a molecular structure of the S-LCEM provided in the present disclosure and there are also flexible connections among chain segments, which promotes the ordered arrangement of S-LCEM molecular chains during a curing process. The highly-ordered arrangement of such mesogenic units is conducive to the formation of a local crystalloid structure, so that a heat flow is transferred along a direction of the ordered molecular chain, which effectively inhibits the scattering of phonons in the S-LCER with high intrinsic thermal conductivity and greatly improves the intrinsic thermal conductivity of the S-LCER with high intrinsic thermal conductivity.

Product of glycidyl ether of a mono or polyhydric phenol
Products of glycidyl ether of a mono or polyhydric phenol as well as methods to manufacture the same. In some instances, the product of glycidyl ether of a mono or polyhydric phenol has an epoxy equivalent weight (EEW) and a hydroxyl value (HV), wherein the epoxy equivalent weight multiplied by the hydroxyl value (EEWxHV) is a value from 1 to 10. A process for producing the product of glycidyl ether of a mono or polyhydric phenol typically includes reacting an epihalohydrin with a mono or polyhydric phenol in the presence of a catalyst to produce a halohydrin ether; and dehalogenating the halohydrin ether to form the product of glycidyl ether of a mono or polyhydric phenol.
