“…The peaks at 2.55 (j,k) and 2.80 (h,i) ppm correspond to the methine resonance of the epoxy groups in trans and cis position, respectively, which demonstrate that SSBR was successfully epoxidized. The peaks at 3.64 (m,) derive from hydroxyl groups [29] which formed during ring-opening reactions after epoxidation and the wide bands in 3100-3600 cm −1 from FT-IR also indicates the presence of hydroxyl groups, but the amount of hydroxyl groups was few and the epoxy degree was little affected. As the reaction progresses, the epoxy degree increases, resulting in an increase of the signals at 2.55 (j,k) and 2.80 (h,i) ppm (trans and cis epoxy) and a decrease of the peak at 5.25 (d.e) ppm (unsaturated 1,4-polybutadiene protons).…”

“…Starting from the previously reported aldehyde‐terminated polybutadiene (ATPB), which has controllable molecular weight and high cis ‐1,4 content, CTPB was now prepared by selective oxidation. Several oxidants, such as H 5 IO 6 /PCC, were tested, but the oxidation of CC double bonds was inevitable.…”

“…The controlled degradation of polydienes by oxidative chain scission or by metathesis of butadiene rubber and natural rubber provided another approach for the preparation of telechelic liquid rubber . In our previous studies, various HTPBs characterized by high cis ‐1,4 content, controllable molecular weight and extremely low glass transition temperature have been prepared by selective oxidolysis of commercial cis ‐polybutadiene rubber followed by reduction …”

“…With the further development of olefin metathesis, adding different types of functional olefins in the olefin metathesis reaction sequence can conveniently introduce ester, carboxyl hydroxyl, and halogen groups at the end of the rubber molecular chain to form polymer materials with specific functions . In addition, the olefin metathesis catalyst can be converted into a hydrogenation catalyst under one atmosphere of hydrogen and be used for the catalytic hydrogenation reaction of unsaturated olefins …”

“…[18][19][20][21][22] In addition, the olefin metathesis catalyst can be converted into a hydro-genation catalyst under one atmosphere of hydrogen and be used for the catalytic hydrogenation reaction of unsaturated olefins. [23][24][25] Nitrile butadiene rubber (NBR) is of primary interest in the automotive industry, on oil fields, and in aerospace due to its excellent oil and chemical resistance, low temperature flexibility, and high pressure and wear resistance. [26][27][28] Despite its many advantages, NBR has some disadvantages, including its swelling in aromatic and polar solvents and a maximum continuous operating temperature below 110°C.…”
