Rubber stabilization

Chemical Reactivity - Reactivity with Water No reaction Reactivity with Common Materials Corrosive, particularly when diluted. Attacks most common metals, including most stainless steels. Excellent solvent for many synthetic resins or rubber Stability During Transport Stable Neutralizing Agents for Acids and Caustics Dilute with water, rinse with sodium bicarbonate solution Polymerization Not pertinent Inhibitor of Polymerization Not pertinent. 

The catalyst, rubber stabilizer, and suspending agent are premixed in styrene and discharged by gravity into the reactor. Since different mixtures are required for each product, these will be added to the styrene manually. This mixture will not be preheated, since it might polymerize.

Dicyclopentadiene was used as another difunctional agent for the synthesis of an oligomeric AO from 4-methylphenol [120] (after tert-butylation, AO 99 was obtained) or diphenylamine [121]. Polymeric aromatic amines for application in rubber stabilization were obtained in the presence of acid catalysts from diphenylamine and l,4-bis(l-hydroxy-l-methylethyl)benzene or 1,4-diisopropylbenzene [122] or from iV,A -diphenyl-l,4-phenylenediamine and a,to-p-xylylenedi-chloride [123]. Polymerization of 2,2,4-trimethyl-1,2-dihydroquinoline in the presence of protic or Lewis adds [1] is very important commerdally. Oligomeric product 100 is an effective AO and AF agent for rubbers.

Phosphoric acid has a central role in fertilizer production, and it is also used as a polishing agent for aluminum car trim and as an additive in soft drinks. The various phosphate salts have many essential applications, from paint stripper (Na3P04) to rubber stabilizer (K3PO4) to fertilizer [Ca(H2P04)2 and (NH4)2HP04].

Nonstaining antioxidants This ciass of antioxidants is subdivided into four groups phosphites, hindered phenols, hindered bisphenols, and hydroquinones. Hindered bisphenols such as 4,4 -thiobis(6-r-butyl-m-cresol) are the most persistent of the four classes of material. Because of then-lower molecular weight, hindered phenols tend to be volatile. Phosphites tend to be used as synthetic rubber stabilizers, and hydroquinones such as 2,5-di-re t-amylhydroquinone are used in adhesives ... 

The term "latex" originally referred to the milky sap of rubber trees and certain plants. This sap was found to be an aqueous medium containing colloids of natural rubber, stabilized by proteins. Laboratory-synthesized polymer colloids were hence described as "synthetic latexes," and finally just "latexes." That term will be used here. Billions of pounds of latexes are synthesized worldwide each year, for a large variety of applications. The reasons for interest in their use in constructing electrochemical labels are...
