Polymerisation method for obtaining butyl rubber based nanocomposite materials |
| abstract |
FIELD: chemistry. n SUBSTANCE: invention relates to polymerisation of isoolefins and polyolefins for producing butyl rubber based polymers filled with silicon dioxide. The method involves dispersion of siliceous nanoclay, containing a quaternary onium ion as a substitute, in an organic solvent which is suitable for use as a polymerisation medium for butyl rubber, particularly methyl chloride. At least one isoolefin monomer and at least one polyolefin monomer are then dissolved in an organic solvent. Further, the isoolefin monomer and polyolefin monomer are polymerised in the presence of nanoclay. Said method enables to obtain a nanocomposite material containing a butyl rubber based polymer intercalated with nanoclay. Addition of nanoclay into the liquid polymerisation medium essentially does not affect the rate of polymerisation. n EFFECT: obtained polymers, which are filled with silicon dioxide, have improved impermeability compared to non-filled polymers. n 16 cl, 2 tbl, 6 ex |
