Abstract
It has unexpectedly been discovered that 1-(1-isocyanato-1-methylethyl)-3-(1-methylethenyl) benzene(m-TMI) can be emulsion copolymerized with other monomers into useful polymers. For example, it has been found that m-TMI can be emulsion copolymerized with diene monomers to produce polymers which contain pendant isocyanate groups. Such pendant isocyanate groups are useful in a variety of applications. For instance, such pendant isocyanate groups can be utilized as sites to which chemical agents, such as antidegradants, can be bound to the polymer. Elastomers which contain such pendant isocyanate groups are of value since they can be crosslinked without employing sulfur. Elastomers of this type which contain pendant isocyanate groups can also potentially be thermo-reversibly crosslinked.
