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.
本发明提供了一种制备低聚
染料的方法,该方法通过使具有碳-碳骨架的第一组分低聚物与具有共反应官能团的
染料组分发生反应来制备低聚
染料,第一组分低聚物由多个聚合单体单元组成,单体单元含有悬垂反应性亲核或亲电官能团。
这些低聚
染料适合用作添加剂,以赋予热塑性聚合物,特别是烯烃聚合物着色或荧光。本发明的低聚
染料在聚合物中具有良好的相容性,而传统
染料通常在聚合物中的相容性或溶解性较差。
