In one embodiment, the butyl rubber is halogenated in hexane diluent at from 4 to 60° C. using bromine (Br 2) or chlorine (Cl 2) as the halogenation agent. The halogenated butyl rubber has a Mooney Viscosity of from 20 to 70 (ML 1+8 at 125° C.) in one embodiment, and from 25 to 55 in another embodiment.

WO2015054685A1 Filler-natural rubber composites Google
Rubber composites containing macro-, micro-, and nano-sized fillers made from agricultural, industrial, and food processing wastes, methods of making the same, and articles fabricated therefrom, are described. In a particular embodiment described herein is a rubber composite comprising a) a rubber component selected from the group consisting of: a natural rubber
Vulcanization is a chemical process in which elastomeric materials are heated with an agent (generally sulfur), an activator, an accelerator, and sometimes a retarder to form a cross-linked molecular network. This results in improved properties such as elasticity, resilience, tensile strength, viscosity, hardness, and weather resistance [3]. 1.

Jan 01, 1996· The natural rubber polymer is nearly 100% cis-1,4 polyisoprene with Mw ranging from 1 to 2.5 x 106. Due to its high structural regularity, natural rubber tends to crystallize spontaneously at low temperatures or when it is stretched. Low temperature crystallization causes stiffening, but is easily reversed by warming.
