Stabilization and controlled degradation of polymers
Additivesfor Polymers

fibre used should be compatible with PA6 and chemically coupled PP (the case with PPG 8045). Contact: PPG gantries Inc, One PPG Place, Pittsburgh, PA 15272, USA. Tel: +I412-434-3131.
Advances in stabilization and controlled degradation of polymers will be held in Lucerne, Switzerland, 2-4 June 1993. Contact: Professor AV Patsis, material ~aborato~, CSB 209, State Universi~ of New York, New Paltz, New York 12.541, USA.
Organic pigments Sandoz ~~ningue discussed the progress made so far in respect of organic pigments as alternatives to cadmium-based products. The first is heat stability. There are still very few long term options for use with engineering materials, There are only three reasonably stable pigments suitabie for use with nylons, (pigments yellow 192, orange 68 and blue 15/3). ABS present similar problems. Yellows 138, 147, 181 and 182, red 151 and 247 and orange 68 are of interest, according to Sandoz, although the reds are not very lightfast.
Additives
Annual
The journal ‘Plastics Engineering’ is currently in the process of compiling its 1993 Additives Annual, which will include information on new materials released between July 1992 and June 1993. Contact: Plastics Engineering, I4 Fairjfield Drive, Brooked, CT ~%~, USA.
Fillers The second problem is distortion, particularly with regard to poIyole~ns. Many pigments act as nucleating sites within the polymer matrix, promoting crystalline growth and hence war-page in the final product. As a result, the choice of colorants for poiyolefins is limited to those that are not soluble in the polymer (soluble colours are widely used for engineering materials). Suitable pigments are yellow 181 and yellow 182. Sandoz summ~ized the current si~ation by saying that repIacements for the traditional workhorse cadmiums are ‘few and far between’ and that to be able to make use of the organic alternatives that do exist means that plastics masterbatching, compounding and processing stages will have to be very precisely controlled.

This book discusses the successful application of fillers, their function, structure, properties, physical chemistry of filled systems, dispersion, morphology, rheology, mechanical properties of filled systems, various applications, tr~spo~ation, storage and safety. Filfers is an important reference book for those who study and apply fillers in polymers, rubber coatings, inks, paper, pharmaceuticals, cosmetics and the food indust~.
