The synthesis of cyclic polymers on a large scale is a challenging task for polymer scientists due to the requirement of ultra-high dilution conditions. In this paper, we demonstrate an alternative method to prepare cyclic polymers with moderate dilution and up to 1 g scale. We employed a simple Williamson etherification reaction to prepare cyclic polymers with a good solvent/non-solvent combination. In this way, various polystyrene (PS) and polyethylene glycol (PEG) cyclic homopolymers were synthesized. Anionic polymerization using high vacuum techniques combined with the postpolymn. reaction was used to generate linear dihydroxy PS precursors. The synthesized linear and cyclic homopolymers were fully characterized using various spectroscopic and anal. techniques, such as size exclusion chromatog. (SEC), matrix-assisted laser desorption/ionization time-of-flight mass spectroscopy (MALDI-TOF-MS), and differential scanning calorimetry (DSC). Detailed NMR spectroscopic studies were also performed to obtain the complete structural information of the synthesized polymers. In addition to this study using 1,4-Bis(bromomethyl)benzene, there are many other studies that have used 1,4-Bis(bromomethyl)benzene(cas: 623-24-5Product Details of 623-24-5) was used in this study.
1,4-Bis(bromomethyl)benzene(cas: 623-24-5) belongs to organobromine compounds. A variety of minor organobromine compounds are found in nature, but none are biosynthesized or required by mammals.Product Details of 623-24-5 The most pervasive is the naturally produced bromomethane.
