: Above a certain molecular weight, chains become physically interlaced, creating a temporary network that resists motion.

The movement of polymers is hindered by their length and surroundings. Polymer Physics

: These account for "excluded volume," meaning two segments cannot occupy the same space. Key Measurements : End-to-End Distance ( : Above a certain molecular weight, chains become

) : A more universal measure of the chain's size relative to its center of mass, used for all architectures (branched, star, etc.). 2. Physical States and Phase Transitions : Above a certain molecular weight
