Polymer stabilizers British: polymer stabilisers are chemical additives which may be added to polymeric materials, such as plastics , to inhibit or retard their degradation.

Degradation and Stabilisation of PVC

Rubber Chemistry and Technology 1 March ; 40 1 : — Poly vinyl chloride PVC holds a major position in the consumption of thermoplastics. In the United Kingdom, from humble beginnings, tons in , production has increased rapidly through the last ten years to the , ton mark in and now accounts for 30 per cent of the total thermoplastics. This dramatic increase is a consequence of the polymer's outstanding properties and its diversity of application at low cost; it is now used in the form of pastes, latexes, solutions, plasticized and unplasticized films, moldings, and extrusions. Originally the advantage of PVC was its ease of processing with existing techniques and equipment developed mainly in the rubber industry, but as the application of PVC products expanded, so the processing conditions became more demanding and the stability of PVC at elevated temperatures became a problem.

Polymer stabilizers

PVC stabilization, the most important aspect of formulation and performance of this polymer, is discussed in details. This book contains all information required to design successful stabilization formula for any product made out of PVC. Separate chapters review information on chemical structure, PVC manufacturing technology, morphology, degradation by thermal energy, UV, gamma, other forms of radiation, mechanodegradation, and chemical degradation. The chapter on analytical methods used in studying of degradative and stabilization processes helps in establishing system of checking results of stabilization with different stabilizing systems. Stabilization and stabilizers are discussed in full detail in the most important chapter of this book.

3rd Edition

It seems that you're in Germany. We have a dedicated site for Germany. Polyvinyl chloride has played a key role in the development of the plastics industry over the past 40 years and continues to be a polymer of major importance. The reasons for its enormous versatility and range of application derive from a combination of the basic structure which gives rise to a relatively tough and rigid material and its ability to accept a range of plasticisers and other additives which can modify its physical characteristics to produce a range of flexible products. Two major problems, however, have tested the skill and ingenuity of PVC technologists since earliest times.

Хотя большинство отделов АНБ работали в полном составе семь дней в неделю, по субботам в шифровалке было тихо. По своей природе математики-криптографы - неисправимые трудоголики, поэтому существовало неписаное правило, что по субботам они отдыхают, если только не случается нечто непредвиденное. Взломщики шифров были самым ценным достоянием АНБ, и никто не хотел, чтобы они сгорали на работе. Сьюзан посмотрела на корпус ТРАНСТЕКСТА, видневшийся справа. Шум генераторов, расположенных восемью этажами ниже, звучал сегодня в ее ушах необычайно зловеще.

 - Сегодня суббота. Чем мы обязаны. Хейл невинно улыбнулся: - Просто хотел убедиться, что ноги меня еще носят. - Понимаю.  - Стратмор хмыкнул, раздумывая, как поступить, потом, по-видимому, также решил не раскачивать лодку и произнес: - Мисс Флетчер, можно поговорить с вами минутку. За дверью. - Да, конечно… сэр.

Приоткрыв дрожащие губы, она попыталась что-то сказать, но слов не последовало. Не спуская со Стратмора ледяного взгляда, Сьюзан сделала шаг вперед и протянула к нему руку с зажатым в ней предметом. Стратмор был почти уверен, что в руке Сьюзан сжимала беретту, нацеленную ему в живот, но пистолет лежал на полу, стиснутый в пальцах Хейла.
