[ 1 ] - بررسی تجربی و محاسباتی سنتز پلی یورتان های ترمیم پذیر بر پایه HTPB با استفاده از واکنش دیلز- آلدر فوران/مالئیمید
The reversibility of the Diels-Alder reaction can be used advantageously in polyurethane materials to endow them with recyclable, thermally reversible properties and self-healing ability to expand their application range. In this paper, linear and crosslink polyurethanes based on HTPB, which exhibit thermal reversibility through Diels-Alder and retro Diels-Alder reactions, were prepared and cha...
[ 2 ] - بررسی اثر زنجیر افزاینده‌ها در تغییر خواص فیزیکی، مکانیکی و انرژی‌زایی بایندرهای پلی‌یورتانی گرمانرم
Polyurethanes are the most well known polymers used to make a binder in high energy material. Polyurethanes aregenerally synthesized by the reaction of diisocyanates and polyols and chain extender.These polymers are often two-phase morphology.Chain extenders are small diols or diamines that are inserted to the hard segment of of polyurethane chain. chemical structure of chain extender, the ...
[ 3 ] - سنتز و بررسی کارایی هیدانتوین گلیسیدیل پلیمر به عنوان عامل پیوندی پلیمری پیشرانه‌های نیتر‌‌آمینی
Bonding agents are important components in solid propellants which affect processing, mechanical, ballistics, safety and aging properties of propellant. In this research, we have synthesized and characterized three types of new polymeric bonding agents by post functionalization of glycidyl azide polymers (GAP) via click chemistry. The interaction of new bonding agents with the surfaces of RDX p...
[ 4 ] - بررسی سیستم های پلیمری حاوی گروه های پر انرژی تترازول(علمی-ترویجی)
Tetrazoles are cyclic aromatic compounds that include four nitrogens and one carbon atom in one ring .These compounds have many applications in civil and military industries. These compounds can produce great amount of N2 after burning and for this reason they have a little environmental contamination and are considered as green explosive materials. Introduction of tetrazoles in polymeric chain...
[ 5 ] - سنتز ، شناسایی و آنالیز کنفورماسیونی مشتقات جدید بیس هیدروکسی اتیل تترازول به عنوان دی ال های پر انرژی(علمی-پژوهشی)
Tetrazoles and their derivatives are insensitive energetic molecules that can be used in the compounding of the high energy material. Herein, two types of bis hyroxyethyl tetrazole compounds have been synthesized using bisnitrile and sodium azide and via consequent alkylation of the reaction product .The structure of all products have been confirmed by 1HNMR, MASS spectroscopy and elemental...
