METHOD FOR IDENTIFYING A BLEND OF NUCLEATORS USEFUL FOR PREPARING A NUCLEATED POLYOLEFIN MATERIAL

The present invention relates to a method for identifying a blend of nucleators with reduced haze in nucleated polyolefin material compared to blends of the same nucleators having different component weight ratios. The method comprises:i) preparing multiple blends of at least two nucleators wherein...

description The present invention relates to a method for identifying a blend of nucleators with reduced haze in nucleated polyolefin material compared to blends of the same nucleators having different component weight ratios. The method comprises:i) preparing multiple blends of at least two nucleators wherein each blend containing the same nucleators in different weight ratios, wherein the blends include one or more blends in which one of the nucleators is a major weight fraction and one or more blends where the same nucleator is a minor weight fraction;ii) determining, for each blend, a minimum dissolution temperature when the blend completely dissolves in individual samples of the same molten polyolefin resin, wherein the concentration of each blend is substantially the same and below the saturation point in the molten polyolefin resin; andiii) identifying a blend that has a lower minimum dissolution temperature than the majority of the blends.
