“…PIB nanofibers are highly desirable due to their hydrophobicity, non-cytotoxicity, and resistance to biofilm formation and fibroblast cell adhesion. The aforementioned characteristics make their nanofibrous mats viable prospects for application in the field of biomedical engineering [ 144 ]. A linear triblock copolymer of PIB called L_SIBS composed of poly(styrene-b-isobutylene-b-styrene), is widely employed as a drug-releasing coating on the TAXUS™ coronary stent [ 145 ].…”

Polyolefins are a widely accepted commodity polymer made from olefinic monomer consisting of carbon and hydrogen. This thermoplastic polymeric material is formed through reactive double bonds of olefins by the addition polymerization technique and it possesses a diverse range of unique features for a large variety of applications. Among the various types, polyethylene and polypropylene are the prominent classes of polyolefins that can be crafted and manipulated into diversified products for numerous applications. Research on polyolefins has boomed tremendously in recent times owing to the abundance of raw materials, low cost, lightweight, high chemical resistance, diverse functionalities, and outstanding physical characteristics. Polyolefins have also evidenced their potentiality as a fiber in micro to nanoscale and emerged as a fascinating material for widespread high-performance use. This review aims to provide an elucidation of the breakthroughs in polyolefins, namely as fibers, filaments, and yarns, and their applications in many domains such as medicine, body armor, and load-bearing industries. Moreover, the development of electrospun polyolefin nanofibers employing cutting-edge techniques and their prospective utilization in filtration, biomedical engineering, protective textiles, and lithium-ion batteries has been illustrated meticulously. Besides, this review delineates the challenges associated with the formation of polyolefin nanofiber using different techniques and critically analyzes overcoming the difficulties in forming functional nanofibers for the innovative field of applications.

“…This elastomer is characterized by an outstanding resistance to gas permeation, high damping properties, excellent chemical (harsh solvents) and oxidative (oxygen and ozone) stability and resistance to stress cracking. 42,65 PIB can be vulcanized by a combination of sulfur and t-butyl peroxide, 66 nevertheless, in many applications isobutylene is generally copolymerized with 1% of isoprene 67 obtaining the so called butyl rubber which can be cured via traditional methods (i.e., sulfur vulcanization 68,69 ). Moreover PIB can be added to other elastomers to form blends especially for increasing the gas permeation resistance 70 and as tackifier.…”

“…39 Typically employed synthetic polymers for gum base are: SBR, polyisobutylene (PIB), isobutylene-isoprene copolymer, paraffin or petroleum wax, polyethylene, polyvinyl acetate (PVAc). [40][41][42] In particular, the elastomer amount ranges from 10% to 20% of the gum base composition. WCGs, however, can be employed as a secondary raw material.…”

This article aims to realize a sustainable rubber compound made in large percentage of secondary raw materials. Waste chewing gum (WCG) has been studied as source of rubber and added in 25% by weight in an ethylene propylene diene monomer based compound in view of a circular economy and eco‐friendly rubber manufacturing. Biobased CaCO3 extracted from waste eggshells was used as extender agent and waste cooking oil from potato chips frying was employed as processing aid. The rubber extracted from WCG resulted to be polyisobutylene (PIB) whereas the main component of the WCG is polyvinyl acetate (PVAc). The addition of the WCG modifies the rheological properties of the rubber compound leading to a better filler–filler and filler–matrix interaction. On the other hand, the presence of both PVAc and PIB leads to lower mechanical properties (max torque 6 vs 10 dNm in curing test) but also higher elongation at break (600% vs 500%). The WCG also increases the self‐adhesion of the rubber and decreases the glass transition temperature allowing for the use of these compounds at lower temperatures thanks to its good tack behavior.
