Synthesis of a unique oligomer by means of the thiol-maleimide reaction of extending 1,1'-(methylenedi-4,1-phenylene) bismaleimide chains for the employment of self-healing polymers

چکیده

Introduction: The Diels-Alder reaction of maleimide and furan groups is being exploited in self-healing materials; hence, it no wonder that with the ownership former, 1,1'-(methylenedi-4,1-phenylene) bismaleimide (BMI) counts as a potential candidate this area. However, displays certain discernible demerits arising from its inflexible structure. Furthermore, group, all likelihood, easily takes part Michael addition thiol under basic conditions. It crucial element opens door for ingredient to be amended view weathering shortcomings. goal research modify structure BMI create new oligomer maleimides at end chains. Method: was synthesized by means 2,2’-(ethylenedioxy) diethanethiol (dithiol) support triethylamine (TEA). In addition, an investigation into possibility happening without base catalyst carried out. application wide assortment modern measurements ranging 1H-NMR FT-IR GPC provided some useful data about molecular weight whether occurred. Result: According information, formation owning terminal functions observed help TEA over 24-hour timescale room temperature, whereas lack impossible. Conclusion: will make major contribution creation healable polymers reliant on mechanism foreseeable future.

investigating the feasibility of a proposed model for geometric design of deployable arch structures

deployable scissor type structures are composed of the so-called scissor-like elements (sles), which are connected to each other at an intermediate point through a pivotal connection and allow them to be folded into a compact bundle for storage or transport. several sles are connected to each other in order to form units with regular polygonal plan views. the sides and radii of the polygons are...
