We describe herein the state of the art following the last 8 years of research into aromatic polyamides, wholly aromatic polyamides or aramids. These polymers belong to the family of high performance materials because of their exceptional thermal and mechanical behavior. Commercially, they have been transformed into fibers mainly for production of advanced composites, paper, and cut and fire protective garments. Huge research efforts have been carried out to take advantage of the mentioned characteristics in advanced fields related to transport applications, optically active materials, electroactive materials, smart materials, or materials with even better mechanical and thermal behavior. These polymers are categorized as high-performance materials because of their outstanding mechanical strength and superior high thermal resistance.

It is one of several nylon polymers. Nylon 12 can be produced through two routes. Ring opening can be carried out by cationic or anionic initiators, although cationic initiators have not been used commercially due to the product being less stable and oxidized relatively quickly in comparison to those produced by activated anionic polymerization monomer casting. Nylon 12 exhibits properties between short chain aliphatic nylons e. Its mechanical properties, such as hardness, tensile strength, and resistance to abrasion, are similar to those of nylon 6 and nylon Low water absorption and density, 1.

For the past decade, market demands for semicrystalline heat-resistant polyamides HPAs with excellent performance and significantly improved heat-resistant temperature has grown rapidly, and they are widely used in the electronic and electrical industry, as light-emitting diodes and in the automobile field as metal replacements. This review addresses progress in HPAs, especially the properties of HPA, patents analysis and polymerization processes. A polyamide PA contains an amide group -CONH- as a recurring part of the polymer chain, it was the first synthetic, semicrystalline polymer with strength- and temperature-resistant properties that allowed its use as a thermoplastic capable of doing some things as well or better than metals. PA has excellent mechanical properties, high resistance to friction, scratching and solvents, is self-lubrication, has shock absorbing and noise absorption performances, so that it became the highest demand engineering plastic and has been widely used in the electronic, electrical and automobile industries, in household appliances, sporting goods, etc. For the past decade, the market demands for HPAs with excellent performance and significantly improved heat-resistant temperature has grown sharply, along with the increased requirements of plastics in the electronic and electrical, automobile, aerospace, military, chemical industries, etc. HPAs are one of the most promising materials in the electronic and electrical industry.

We apologize for the inconvenience...

PA material, polyamide or commonly called nylon, is manufactured by Ensinger in standard stock shapes for machining in sheet, rod and tube. There are often numbers associated with nylon plastics types such as 6, 66, 12 and These numbers relate to the molecular structure of the nylon polymer and each structure type will have different properties.

Сьюзан покачала головой. Стратмор наморщил лоб и прикусил губу. Мысли его метались. Он, конечно, с легкостью мог набрать код лифта и отправить Сьюзан домой, но она нужна ему. Она должна помочь ему найти ключ в компьютере Хейла.

Сьюзан собралась с мыслями и шагнула в дверной проем. Компьютер зафиксировал ее прибытие. Хотя Сьюзан практически не покидала шифровалку в последние три года, она не переставала восхищаться этим сооружением. Главное помещение представляло собой громадную округлую камеру высотой в пять этажей. Ее прозрачный куполообразный потолок в центральной части поднимался на 120 футов.

1 Introduction

Я попросил оказать мне личную услугу. И он согласился поехать. - Конечно, согласился. Вы же мой шеф. Вы заместитель директора АНБ. Он не мог отказаться.

Ключ к Цифровой крепости, внезапно осенило ее, прячется где-то в глубинах этого компьютера. Когда Сьюзан закрывала последний файл, за стеклом Третьего узла мелькнула тень. Она быстро подняла глаза и увидела возвращающегося Грега Хейла. Он приближался к двери. - Черт его дери! - почти беззвучно выругалась Сьюзан, оценивая расстояние до своего места и понимая, что не успеет до него добежать.

Пуля попала в корпус мотоцикла и рикошетом отлетела в сторону. Беккер изо всех сил старался удержаться на шоссе, не дать веспе съехать на обочину. Я должен добраться до ангара. Интересно, увидит ли пилот лирджета, что он подъезжает. Есть ли у него оружие. Откроет ли он вовремя дверцу кабины.

 Выходит, нас атакует всего лишь первый набросок червя Танкадо. - Набросок или отшлифованный до блеска экземпляр, - проворчал Джабба, - но он дал нам под зад коленом. - Не верю, - возразила Сьюзан.  - Танкадо был известен стремлением к совершенству. Вы сами это знаете.

 - Уничтожить всю нашу секретную информацию? - Сьюзан не могла поверить, что Танкадо совершит нападение на главный банк данных АНБ. Она перечитала его послание. СЕЙЧАС ВАС МОЖЕТ СПАСТИ ТОЛЬКО ПРАВДА - Правда? - спросила .

Это означает конец нашей разведки. Но мысли Сьюзан были далеко от политических последствий создания Цифровой крепости. Она пыталась осознать истинный смысл случившегося. Всю свою жизнь она посвятила взламыванию шифров, отвергая саму возможность разработки абсолютно стойкого шифра.

 - Тебе не нужно оставаться до конца смены. Мы с мисс Флетчер пробудем здесь весь день. Будем охранять нашу крепость.
