《Polymerization of N-vinyl caprolactam by ultrasound aided dual-sited phase transfer catalytic conditions》 was written by Marimuthu, Elumalai; Murugesan, Vajjiravel. Recommanded Product: 1,4-Bis(bromomethyl)benzeneThis research focused onvinyl caprolactam phase transfer catalyzed polymerization. The article conveys some information:
This work demonstrates the successful polymerization of N-vinyl caprolactam using dual-sited phase-transfer catalyst and potassium persulfate as conventional radical initiator in cyclohexane-aqueous media at 60 ± 2°C under normal and ultrasound environment with 45 kHz power of 550 W. Dual-sited phase-transfer catalyst acts as a gear to accelerate the reaction in a two-phase system and along with ultrasound circumstance reaction rate was effectively improved. We observed that the polymerization rate was significantly increased with an increase of concentration of different reaction parameters and also presence of ultrasound environment rate was doubled than with normal condition. Activation energy value of polymerization reaction validates the doubling of polymerization rate. The various reaction parameters (frequency, monomer, initiator, catalyst, and temperature) on the polymerization rate were explored under normal and ultrasound condition. Acquired poly(N-vinyl caprolactam) was validated and characterized by different analyses. In the experiment, the researchers used 1,4-Bis(bromomethyl)benzene(cas: 623-24-5Recommanded Product: 1,4-Bis(bromomethyl)benzene)
1,4-Bis(bromomethyl)benzene(cas: 623-24-5) belongs to organobromine compounds.Organobromine chemicals are produced naturally by an array of biological and other chemical processes in our environment. Organobromine compounds are produced naturally by marine creatures (sponges, corals, sea slugs, tunicates, sea fans) and seaweed, plants, fungi, lichen, algae, bacteria, microbes, and some mammals.
