More detailed compounding suggestions and additives information can be found in the technical bulletins published by ACM and additives suppliers (50—54). 

Figure 1.1 shows that the methods of manufacturing (semi-)finished plastic parts involve various players equipment manufacturers, polymer producers, additive suppliers, compounders and final processors. It can be safely assumed that the compounder will continue to be the main customer for additives and additive concentrates also in the future. Finally, the recently established Plastics Additive Museum (Lingen, Bavaria), by a pioneer in PVC additives (Barlocher GmbH), shows that the business is coming to age. 

Whatever the approach, the result is a difficult-to-analyse system. Such options suit polymer producers better than additive suppliers. Aromatic polymers (PPO) have been mentioned as char-forming FRs. Polymeric UV absorbers, blended in proper proportions with commercial plastics, have potential use as stabilisers for fibres, films and coatings. Several monomeric stabilisers containing a vinyl group were homopolymerised and used as stabilisers for PE, PVC, acrylates, polystyrene, cellulose acetate and several vinyl polymers [55].

To resolve the problem, personnel from the gasoline additive supplier worked with the customer to collect service station gasoline samples, customer fuel filters, and samples of gasoline from the retailer s local service stations and from the fuel distribition terminal. All of these samples were thoroughly analyzed. Also, January fuel delivery records were closely audited. 

When wax crystal modifiers are added to cold fuel, even to fuel well above its cloud point, modifiers may not dissolve properly. The polymeric nature of wax crystal modifiers makes them quite viscous at low temperatures. Additive suppliers will often provide modifiers in a highly dilute form (i.e., 10% or 20% solution), so they will remain fluid at low temperatures. 

For the past 16 years, he has been a Research Group Leader for ONDEO Nalco Energy Services, located in Sugar Land, Texas. He works daily with laboratory chemists to provide technical service and support to a variety of customers worldwide such as major oil refiners, independent fuel marketers, aftermarket additive suppliers, fuel brokers, and others in the petroleum industry.

EPA) to aid in registering chemicals under the federal Toxic Substances Control Act (TSCA) of 1976. CAS numbers are assigned to generic refinery process streams, such as kerosene and lube base stocks, that contain no additives. Petroleum products containing additives are termed "mixtures" by the TSCA and, as such, do not have CAS numbers. All chemical substances used in such mixtures are assigned CAS numbers and must be listed with the EPA by the refiner or the additive supplier. 

A variety of methods for evaluating antioxidants in polypropylene has been developed during the past several years. Polymer producers, end-use manufacturers, additive suppliers, academicians, and others have developed widely disparate test methods, all of which presumably yield the same results—i.e., the test methods rate the antioxidants and antioxidant systems in the same relative order of effectiveness. Many of these test methods are useful tools in distinguishing unstabilized polymer, moderately stabilized polymer, and highly stabilized polymer systems. Today, all of the polypropylene producers offer highly stabilized polymers. Effective antioxidants are available from several additive suppliers. How does one select the best antioxidant or polymer formulation for a particular end use This paper compares the results obtained by various test methods used to evaluate the two basic types of oxidative stability, processing stability and end-use or environmental stability. The correlation or lack... 

These are exceptions, however. The world s largest additives producer for plastics, Ciba-Geigy, remains, for its part, at the sole service of its downstream customers and tries not to appear as a competitor. This is also the position of other additive suppliers like American Cyanamid, Ferro, Witco, UniRoyal Chemical in the United States, AKZO, SFOS (Rhone-Poulenc) in Europe, Adeka Argus and Dai-ichi Kogyo Seiyaku (DKS) in Japan. 

Processing with the styrene monomer requires that precautions have to be taken to ensure the proper removal and handling of this toxic material. Legal limits in the workplace have been set up by regulations. Other monomers used include diallyl phthlate (DAP), para-methylstyrene (PMS), vinyl acetate (VA), vinyl toluene (VT), adding paraffin wax, and styrene suppressant additive. Suppliers and fabricators continue to target in the reduction of styrene monomer quickly, effectively, and economically. A wide variation in properties can be obtained by changes in polyester formulation. 

The PVC industry consists of resin producers, compounders, additive suppliers and processors. Most processors specialise in processes linked to either PVC-U or PVC-P applications. In some cases, such as pipe and window frame manufacturing, the processed PVC is marketed directly by the processor. In other cases, the processor passes on the PVC in semi-finished form to another company.

It reacts with zinc oxide (1, 1294 additional suppliers Alfa Inorganics, ROC/RIC) to give isopropyl isocyanate (S). The yield is high if the complex (I) is not isolated owing to its high sensitivity to moisture. The reaction of (I) with silver oxide was not successful owing lo the violence of reaction. Reaction of (I) with sodium acetate gave (S) in 24% yield.
