Abstract
A method for producing a polymer, which contains: bringing a monomer containing a vinyl bond into contact with a compressive fluid and melting or dissolving the monomer containing a vinyl bond, followed by carrying out addition polymerization of the monomer containing a vinyl bond in the presence of an initiator.
Claims15
A method for producing a polymer, comprising:
- bringing a monomer containing a vinyl bond into contact with a compressive fluid and melting or dissolving the monomer containing a vinyl bond, followed by carrying out addition polymerization of the monomer containing a vinyl bond in the presence of an initiator.
A polymer product, comprising:
- an organic solvent in an amount of less than 5 ppm;
- and
- monomer residues in an amount of 2% by mass or less, and
- wherein a number average molecular weight of the polymer product is 15,000 or greater, and a molecular weight distribution (Mw/Mn) represented by a ratio of a weight average molecular weight of the polymer product to the number average molecular weight is 1.2 or less.
