Перевести без переводчика: Synthetic polymers and their application
Polymers are the dynamic part of industry, particularly plastics and fibres. A polymer is a substance consisting of molecules and characterized by its viscosity colour and by its softening points. Until recently it was thought that the properties of the polymers were determined only by the chemical structure of their molecules. Chemists after many years of research have established that the properties of polymers produced are largely determined by the pattern of their big molecules. The properties of polymers depend on their super-molecular structure.
Polymers just like metal a can be alloyed, i.e. groups different in composition may be introduced into the structure of the polymers. A study has been made of possible variants of structural patterns of different polymers and of ways of developing the required structures. This has opened up the possibility for developing substances with scheduled properties.
High molecular compounds possessing a great variety of valuable properties, they can therefore be used in a wide range of things.
The main concern of researchers and engineers is to improve the quality of mass produced goods.
The so-called "aging" of material is a result of deterioration in the properties of polymers due to chemical and physical changes caused by the effect of light, heat and humidify. Many laboratories are conducting research to prevent these processes.

Синтетические полимеры и их применение
Полимеры являются динамичной частью промышленности, особенно пластмасс и волокон. Полимер - это вещество, состоящее из молекул и характеризующееся своей вязкостью, цветом и температурой плавления. До недавнего времени считалось, что свойства полимеров определяются только химической структурой их молекул. Химики после многих лет исследований установили, что свойства производимых полимеров в значительной степени определяются узором их больших молекул. Свойства полимеров зависят от их сверхмолекулярной структуры.
Полимеры, как и металл, могут быть сплавлены, то есть в структуру полимеров могут быть введены группы различного состава. Было проведено исследование возможных вариантов структурных узоров различных полимеров и способов разработки необходимых структур. Это открыло возможность разработки веществ с заданными свойствами.
Высокомолекулярные соединения, обладающие множеством ценных свойств, могут быть использованы в широком спектре вещей.
Основным заботой исследователей и инженеров является улучшение качества массово производимых товаров.
Так называемое "старение" материала - результат ухудшения свойств полимеров вследствие химических и физических изменений, вызванных воздействием света, тепла и влаги. Многие лаборатории проводят исследования по предотвращению этих процессов.
