38. Encyclopedia Britannica, Volume 18 (A New Survey of Universal knowledge ; Plants to Raymund of Tripoli) published by Encyclopedia Britannica Limited, 1961 Edition, defines plastic as under :

"The term plastic derived from the Green plastikos, appears to have been used first as a suffix implying growing developing and forming. Later it was used as an adjective meaning capable of being formed. The manufacture of pottery and earthenware depends on the plastic qualities of the clay, the making of the glass and plastics and the use of the putty asphalt and cement are all depending upon the plasticity of the product."

Reference may also be made to Van Nostrand's Scientific Encyclopedia, 4th Edition, 1968, published by D. Van Nostrand Co. Inc. to which both the petitioner as well as the respondent refer.

41. It is stated in the affidavit of Mr. G.D. Chatterjee on behalf of the respondent in support of their assertion that polymer chips are plastic that because synthetic fibres forming polyamide (including Nylon) are essentially thermoplastic and, therefore, must be deemed to be plastic. Mr. Palkhiwala strongly protested against the above said assertion and maintained that in order to find out whether polymer chips are plastic or not it is meaningless to call any of them as thermoplastic as being irrelevant. According to him, the thermoplastic only means a material which can be softened to a pliable mass by heating, then shaping it to a desired form which is retained OH cooling to the solid state. According to him thermoplastic is a quality of material which may be common to various items and it would be wrong to include all of them under the head 'Plastic'. In this connection reference is made to the definition of thermoplastic in British Plastics Year Book, 1967, published by Life Books Limited, Stamdord Street, London, where it is mentioned as under :

45. The counsel for the respondent contended that the above extract supports his contention that fibre polymer should also be regarded technically and scientifically as plastic. The counsel also brought to my notice the following extract from Van Nostrand's Scientific Encyclopedia, IV Edition, published by D. Van Nostrand Company Inc. Page 1368.--Nylons are durable and tough plastics which can be used for noiseless gears, oil less bearings, and many other uses, especially as fibres.

Counsel for the petitioner, however, pointed out that plastic has restricted meaning and does not apply to polyamides which fall in the category 'suitable for textile fibre spinning' such as Polymer chips obtained by the petitioner.

47. The counsel for the petitioner, however, submitted that no much reliance can be placed on this Dictionary as the author has mentioned that he has found differences of opinion existing between companies in the same country as a term used in one country may mean something rather differently. In this connection it was pointed out that the mention of Titanium Dioxide as an inorganic pigment is not mentioned in 'Encyclopedia of Polymer science and Technology' Volume 10, Edited by Herman F. Mark & others; published by Inter science Publishers, New York, wherein a table is given of different inorganic pigments, including of the class Oxides but no mention is made of Titanium Dioxide. The suggestion is that if this entry does not include Titanium Dioxide as one of the inorganic pigment the mention of it in the Dictionary of Plastics, by J.A. Wordingham and R. Reboul is inaccurate.
