- OLIGOMERIC DYES AND PREPARATION THEREOF
-
The invention provides a method for preparing an oligomeric dye by reacting a first component oligomer, having a carbon-carbon backbone, comprising a plurality of polymerized monomer units comprising pendant reactive nucleophilic or electrophilic functional groups; and a dye component having a co-reactive functional group.These oligomeric dyes are suitable for use as additives to impart coloration or fluorescence to thermoplastic polymers, particularly olefinic polymers. The oligomeric dyes of the present invention advantageously are compatible in polymers where conventional dyes often have poor compatibility or solubility.
