| titleOfInvention | Method for isolating polyphenylene ether polymer resins from solution |
| abstract | A method of removing substantially all solvent from a solution containing a polyphenylene ether polymer resin with little by-product formation (less than 250 ppm) is provided. The method employs a wiped thin film evaporator with a cylindrical heating chamber operating under conditions that satisfy the relationships defined by Equations I and II: 5.3*10<24>RL delta exp(<-24123/T>)/m < C (I), 100- (4960AP/Tm) < C (II); yields are maximized wherein values for feed rate (m) and percent solids (C) are selected to provide a maximum value for the output, Q, determined from the equation m * C = Q and the melt viscosity of the polyphenylene ether product is less than 50,000 centipoise at the operating temperature of the cylindrical heating chamber. |
