Abstract
This invention utilizes methods of emulsion chemistry to derivative polymers, as distinguished from the synthetic methods of the prior art, whereby such polymers are derivative in a true solution. The derivative polymers are useful in that they may be readily reacted with small polymers or other molecules to form new polymeric entities. The new polymeric entities may be further derivative during the step of interracial dramatization, or may be provided for reaction to the product in a subsequent step to form the target product.
