Molecular Weight Distribution (MWD) describes the variation in molecular weights within a given polymer sample, significantly affecting its physical properties and processing behavior. Understanding MWD is crucial for tailoring polymers for specific applications, as it influences parameters like viscosity, tensile strength, and thermal stability.

Viscosity is a measure of a fluid's resistance to deformation or flow, often perceived as 'thickness' or internal friction. It is a crucial property in fluid dynamics, affecting how substances move and interact under various forces and conditions.

Tensile strength is the maximum amount of tensile stress that a material can withstand while being stretched or pulled before breaking. It is a critical property for materials used in construction, manufacturing, and engineering applications to ensure structural integrity and safety.

Thermal stability refers to the ability of a substance to maintain its physical and chemical properties at elevated temperatures. It is a critical factor in determining the suitability of materials for high-temperature applications and influences their degradation, decomposition, or phase change behaviors.
