Definitions
- Butyl rubber is a synthetic elastomer typically comprised of a copolymer of isobutylene and isoprene. Butyl rubber was first produced with the advent of World War If and the associated limited supply of natural rubber.
- Butyl rubber has a low degree of permeability to gases due to uniformity in the polyisobutylene portion of the butyl chains and the ease of packing provided by this uniformity.
- Butyl rubber can be 8-10 times more resistant to gas permeability than natural rubber and also has excellent resistance to heat, steam and water.
- the low degree of permeability to gases accounts for a frequent use of butyl rubber in inner tubes and tire inner liners.
- butyl rubber is advantageously used in air cushions, pneumatic springs, air bellows, accumulator bags, and pharmaceutical closures.
- the thermal stability of butyl rubber makes it suitable for construction of tire-curing bladders, high temperature service hoses, and conveyor belts for handling hot-materials.
- a polymer such as polypropylene or nylon is then added to further separate the layers of the clay. Moreover, the polymer is attracted to the organic salt and therefore penetrates between clay layers. The large molecule size of the polymer serves to counteract any remaining Van der Waals interactions between the layers and the clay becomes fully exfoliated, i.e. separated into discrete layers.
- a first aspect of the invention is to provide a polymeric exfoliant that is an exfoliant for clay.
- a further aspect of the invention is to provide a method for making an organo-modified clay product which can be exfoliated into butyl rubber by dry mixing.
- FIG. 5 shows comparative small angle x-ray scattering (SAXS) for PIB 2 QS 2 exfoliated clay with and without low molecular weight surfactant contributions as dry mixed in butyl rubber.
