Degree of Polymerization

Degree of polymerization means the number of repeat unit of a polymer molecule for instance if there are 1000 repeat units in polymer molecule. So the degree of polymerization (D.P) is 1000.
Function of Degree of polymerization: Degree of polymerization plays a good role in forming a polymer. Because the size of a polymer molecule depends on the number of repeat unit which represent the degree of polymerization so a polymers behavior is also depends on degree of polymerization, the polymer D.P. is high, its luster, dyeing, and strength as cross degree of polymerization is 2500-3000. So its physical and chemical properly is no good.
