Abstract
The present invention provides a molecular blended polymer that includes two or more types of polymers blended at the molecular level. At least one monomer is polymerized in the presence of two or more kinds of catalysts supported on a mesoporous molecular sieve having a pore size of 20 Å to 500 Å. The polymerization occurs in the pore of the mesoporous molecular sieve and is controlled at the molecular level. Thus, the polymer material is controlled extremely well and the function and physical properties of the polymer material are greatly enhanced.
