Usage

General Description

2,2'-[[1,1'-biphenyl]-4,4'-diylbis(oxy)]bisethanol, also known as bisphenol A diglycidyl ether, is a chemical compound used in the production of epoxy resins. It is commonly used in the manufacturing of coatings, adhesives, and electronic components. However, there is concern over its potential health risks, as it is classified as an endocrine disruptor and has been linked to various adverse health effects, including reproductive issues, hormone disruption, and cancer. Due to these concerns, the use of this chemical has been restricted in certain regions, and efforts are being made to find safer alternatives for its industrial applications.

Synthesis and characterization of block copolymers of polystyrene and thermotropic liquid crystalline polyesters

A series of block copolymers containing a thermotropic liquid crystalline polymer and an amorphous polystyrene have been synthesized. The block copolymers were prepared by solution polycondensation of α,ω-dicarboxylic acid-terminated polystyrene with 4,4′-dicarboxy-1,6-diphenoxy-hexane and 4,4′-bis(2-hydroxyalkyloxy)biphenyls in a mixture of triphenylphosphine, hexachloroethane, and pyridine. The obtained polymers were fractionated to isolate the pure block copolymer. The block copolymers were characterized by FTIR spectroscopy, differential scanning calorimetry, thermogravimetric analysis, optical polarizing microscopy measurement. Optical polarizing microscopy measurements verify the presence of a smectic liquid crystalline phase for the block copolymers. The block copolymers represent a microphase-separated morphology, i.e., both amorphous and liquid crystalline properties were displayed by the polystyrene and liquid crystalline polyester segments respectively.

One-pot synthesis of cyclophane-type macrocycles using manganese(iii)- mediated oxidative radical cyclization

Cyclophane-type macrocyclic compounds from 21 to 56 members having two fused dihydrofuran rings were synthesized by the manganese(iii)-mediated oxidation of terminal dienes with bis(3-oxobutanoate)s containing aromatics. The reaction detail, characterization and reaction pathways are described. The Royal Society of Chemistry 2011.
