| titleOfInvention | Method for controlling a polymerization rate of styrene resins |
| abstract | The method for controlling a polymerization rate, in a continuous radical polymerization of mainly styrene monomer using a complete mixing type reactor, without substantially changing an average molecular weight of a polymer formed, comprising the steps of: (a) keeping a polymerization temperature substantially constant at t( DEG C.), (b) setting a feeding rate of the styrene monomer to A times larger rate than that in a polymerization conducted in the absence of a radical polymerization initiator, and (c) controlling an amount of the radical polymerization initiator added in the range of from (0.1/n)x10-3 to (2.0/n)x10-3 mol per 1 liter of the monomer, n being a number of radical generating functional groups present in one molecule of the radical polymerization initiator, such that a polymer concentration x satisfy the mathematical expression: x>/=0.3t+6x(A-1)+12 and that x be kept substantially constant, wherein A represents a ratio of a polymerization rate after being controlled to a rate of polymerization conducted in the absent of the radical polymerization initiator. The method can easily and as desired control the polymerization rate using any desired radical polymerization initiator. |
