Vogel, Wilfried; Heitz, Walter published the artcile< Liquid-crystalline poly(4-hydroxybenzoates) with phenethyl side chains>, Recommanded Product: 2-Bromo-4-nitrobenzoic acid, the main research area is polyhydroxybenzoate liquid crystal phenethyl substituent; statistical substituent polyester liquid crystal.
An important means to decrease the m.p. of liquid-crystalline polymers is the statistical arrangement of substituents along the chain. Thermotropic liquid-crystalline poly(4-hydroxybenzoates) bearing one phenethyl substituent in different positions of the monomer were synthesized via melt polycondensation. The relation between the arrangement of the substituent along the polymer backbone and the properties of the polyesters was investigated. The 2 polyesters with the substituent either in 2- or 3-position revealed highly crystalline and poorly soluble products. In contrast to this, the random copolyester is an amorphous and well-soluble polymer.
