Controlling Dispersity

This lecture explores the concept of dispersity in polymer science, discussing whether it is sufficient to describe molecular weight distribution. It delves into strategies to control dispersity, such as polymer blending, initiation regulation, tailored catalyst concentration, and the use of additional reagents. The impact of dispersity on polymer properties, self-assembly behavior, and structure is also examined, along with the effects of dispersity on physical properties like Young's modulus. Various parameters like asymmetry factor, skewness, and kurtosis are explained to describe molecular weight distributions, providing a comprehensive understanding of the topic.
