Nearly 55% of world patents in polymer blends and alloys are issued in Japan, and only a fraction of those is ever available in English translation (Chemical Abstracts, the most extensive source, includes short notes on less than 80% Japanese Patents). This creates two problems: inventors from countries other than Japan do not have sufficient information on new developments and many inventions are contested because they infringe on already given rights. Japanese consumer products have dominant position in various areas of world market. It is less recognized that this competitive advantage is partly due to a leadership position in materials used. Cars, radios, cameras, computers, etc., have high content of the engineering plastics - subject of the book. Due to a large number of patents issued in Japan on polymer blends, several volumes were already published with aim to report currently filed applications. The currently available volumes are listed below. Each volume contains a complete review of patent applications in Japan in the area of blends.
Each patent is described according to the same pattern, including:
Date of laid open
Date of application
Names of inventors
Name of company
Composition of materials and methods of components preparation
Method of blend production
Methods of blend processing in applications
Advantages of blend.
Following this consistent pattern of presentation and precise indexing system results in book easy to use (required information can be retrieved in minutes). Chemical formulas allow easy comparison with other similar products. Many other searches are possible. For example, polymers and polymer combinations used for particular application, activity of a particular company in polymer blends and the direction of their efforts, advantages of blending with various polymers, etc. The volumes contain description of from 800 to over 1000 patents issued in a current year.
Expected readership includes the specialists in academia and industry in polymer chemistry, synthesis, technology, and processing, material science, molding, extrusion, new final product development, product design. Book is an invaluable source for patent offices and lawyers.
