Title:
LOW VISCOSITY POLYMER POLYOL CHARACTERIZED BY HIGH HYDROXYL NUMBER
Document Type and Number:
Japanese Patent JP2007077396
Kind Code:
A
Abstract:
To provide a new polymer polyol having a low viscosity and a high hydroxyl number; and to provide a method for producing the new polymer polyol.
The polymer polyol has the hydroxyl number of ≥20, a solid content of about 30 to about 65% by weight and a viscosity that is less than or equal to be[2.7c]. The polyol comprises the reaction product of a base polyol, a preformed stabilizer and at least one ethylenically unsaturated monomer, in the presence of a free-radical polymerization initiator and at least one polymer control agent. The base polyol has a hydroxyl number of 60 to 1,900, a functionality of 1 to 10, and an equivalent weight of 30 to 900.
