Abstract A new approach is presented toward obtaining improved properties in Butyl rubber vulcanizates through chemical modification of the Butyl rubber polymer by N-methyl-N,4-dinitrosoaniline. Chemical modification by this additive may be carried out in a Banbury mixer at conventional mixing times and temperatures. The use of modified polymer is advantageous in both black- and non-black-loaded stocks and is advantageous also with respect to variation over the spectrum of vulcanizing systems which are normally used with Butyl rubber. A successful plant demonstration of chemical modification has been carried out.

Dissolution and regeneration of cotton cellulose using ionic liquids as solvent was investigated. In this paper, modification of celluloses with maleic anhydride (MA) was carried out in ionic liquid,1-allyl-3-methylimidazolium chloride(AmimCl).The maleylation celluloses with degrees of substitution (DS) between 0.85and 1.46 were accessible in IL. The effects of reaction time, temperature and mass ratio of the MA in cellulose were investigated. These maleylation celluloses were characterized by infrared spectroscopy, thermogravimetric analysis (TGA). Experiments showed that the optimal conditions for grafting were: mass ratio of maleic anhydride and cotton cellulose 0.8; reaction time of 90 min; temperature of 80 °C.
