“…Although the mechanical properties of the resulting copolymer were improved, the synthesis itself was complicated [ 19 , 48 , 49 , 50 ]. Bis-(chloromethyl) Oxetane copolymer with THF was described by [ 51 ]. The synthetic route is also complicated author provided DSC of Bis-(chloromethyl) Oxetane–THF copolymer showed exothermic decomposition with T max at 371

Energetic oxetanes, a group of energetic binders (EBs), are the focus of this review. We briefly introduce the role of binders and the difference between EBs and traditional “non-energetic” polymer binders, followed by a discussion of the synthesis and key properties of polyoxetanes. Priority is given to recent works, but a long-term perspective is provided where necessary, to illustrate the development of this field and the most relevant emerging trends. New reports on methods of obtaining oxetane polymers are presented; concerning the possibility of using a new catalyst, water: Al(C4H9)3, or the ratio of comonomers on the properties of the obtained binders. The synthesis of copolymers with the use of polymers with an oxetane ring and polyethers, polybutadiene terminated with hydroxyl groups and poly (3-difluoroaminomethyl-3-methyloxetane) is discussed. The latest developments in crosslinking reactions and crosslinking agents used are also described. The primary challenges faced by the field are identified and a perspective on the future development of polyoxetane EBs is presented.

l‐glutathione, a naturally occurring environmental friendly amino acid, was used as an initiator towards the ring opening polymerization (ROP) of ɛ‐caprolactone (CL) followed by the ROP of tetrahydrofuran (THF). The thiol group of l‐glutathione reduces Ag+ ions and chemically bound to the surface of Ag nanoparticles. The ROP of CL was carried out at 160 °C under nitrogen atmosphere in the presence of stannous octoate(SO) as catalyst whereas the ROP of THF was carried out at 45 °C for 24 h in the presence of phthalic anhydride (PAH) as a comonomer. The synthesized homo, di and nano Ag end capped diblock copolymers were characterized by FTIR, DSC, TGA, FESEM, high resolution transmission electron microscope (HRTEM), EDAX, GPC, nuclear magnetic resonance (NMR), Fluorescence and CD. Further the application of diblock copolymer was tested for splinting activity. The catalytic reduction of 4‐nitrophenol (NP) in the presence of nano Ag end capped diblock copolymer was carried out with the assistance of sodium borohydride as a reducing agent and the apparent rate constant (kapp) was determined and compared with the literature values. © 2016 Wiley Periodicals, Inc.
