Review Article: Butyl and Halo-Butyl Rubbers
Abstract: Butyl and halo butyl rubbers are key raw materials for various industries due to their exceptional properties, like permeability to gases, high chemical resistance, and durability. Butyl rubber (IIR) is composed of isobutylene with small amounts of isoprene, offering a low permeability to gases, making it ideal for applications in the automotive, medical, and consumer goods. Butyl Rubber is non-polar nature and possess excellent insulation properties which further enhance its …

Synthesis of Bromobutyl Rubber: Effect of Reaction Temperature and Time on Bromobutyl Rubber Microstructure
Abstract: Butyl rubber is prepared by cationic polymerization process either by solution or slurry phase by randomly copolymerizing isobutylene with small amount of isoprene (1-3 mol %). It has good air impermeability and oxidative stability and thus finds extensive use in inner tube applications. The presence of unsaturation in the form of isoprene units in butyl rubber provides a means of enhancing useful properties of this important commodity elastomer by incorporation …

Investigation of the Compatibility of Binary and Ternary Polymer Systems
Abstract: We have obtained mechanical strength of materials as a result not by synthesizing new polymers, but by using industrial polymers. We have developed a technology for obtaining new composite materials based on industrial multi-tonnage polymers of high-strength polyethylene (HSPE), polyvinyl chloride (PVC), polyurethane thermoplastic elastomer (DUTEP), butyl rubber (BR), chlorocarboxylate polyethylene (CCPE), ethylene propylene rubber (EPR). To obtain a composition from these polymers, their mixture compatibility was first determined using …

Facile Approach to Epoxidize Elastomers & Its Silica Composite for Green Tyre Application
Abstract: Rubber epoxidation is usually carried out to serve dual purpose, to introduce the functionality, and to enhance the polymer – filler interaction. In general, epoxidation of elastomers having unsaturation in backbone adopt conventional refluxing and batch process which makes the synthesis complex as well as time consuming. In view of this, a novel process of epoxidation through sonication technique is identified as simple and efficient process. Synthetic rubbers containing unsaturation …

Synthesis of Brominated Poly (Isobutylene-co-Isoprene) Based Ionomers and Its Applications
Abstract: Reactive bromobutyl rubber and its modification have been studied in detail. These reactive bromobutyl rubber was converted to ammonium and phosphonium functionalized bromobutyl rubber using triphenyl phosphine (PPh3) and 4-Dimethylaminopyridine (4-DMAP). Mechanical properties of synthesized ionomers are found comparative with butyl rubber. Pharma stopper was made from synthesized phosphonium ionomer that may be useful for pharma industries due to its self-healing characteristics which can help to preserve the properties of …

Studies on Functionalized Nonwoven Polypropylene Fabric for Antibacterial & Antiviral Properties
Abstract: Nonwoven polypropylene (NWPP) fabric is a versatile material used predominantly in medical field for hygiene products and for PPE applications. The application of NWPP is limited in disinfectant area due to lack of antimicrobial properties and its non-polar nature. The coating of antimicrobial agents on NWPP fibre is expected to lower down the intensity of communicable microbial infections. The present study involves the surface functionalization of NWPP fibre via plasma …
