A molecular weight of a polymer is measured by a process including steps of: heating a polymer portion with a heating device, measuring, with a temperature measuring device, the difference between temperatures of at least two points of the polymer portion at each of which the polymer portion is subjected to a thermally different influence from each other by the heating device, and estimating the molecular weight of the polymer which corresponds to the difference between the temperatures obtained by the measuring step according to a relationship between the temperature difference and the molecular weight of the polymer which relationship has been beforehand obtained.

Method for measurement of polymer molecular weight based upon a

A stirring reactor for a viscous material. The reactor comprises a stirring vessel; a revolvable shaft provided in the vessel; a surface layer stirring vane provided on the revolvable shaft in the vicinity of interface of the gas and the liquid to be stirred; a stirring vane having at least a pair of radially directed multiple portion blades which extend radially towards the inner wall, a first of which blade portions is fastened on the revolving shaft below the upper layer stirring vane and the other of which blade portions extends outwardly radially from said first portion to terminate close to the inner wall of the vessel; and baffle plates provided on the inner side wall at positions substantially parallel to the surface layer stirring vane, and at a height between the heights of any stirring vanes having multiple blades.
