Zusammenfassung:	To provide a rheometer for measuring the polymerization rate, capable of releasing gas generated during the polymerization reaction to the outside of a system, and a method capable of measuring the polymerization rate by reproducing the polymerization behavior occurring in the actual scene by providing a jig that can desirably control the atmosphere of the sample surface during the polymerization reaction.SOLUTION: A viscoelasticity measurement jig for a rheometer includes: a shaft; an upper plate of a parallel plate concentrically attached to the tip of the shaft; and a lower plate of the parallel plate. The upper plate of the parallel plate is a porous body having a through-hole.SELECTED DRAWING: Figure 2 【課題】本発明の課題は、レオメータによる重合速度の測定において、重合反応時に発生するガスを系外に逃がすことができ、且つ、重合反応時の試料表面の雰囲気を自由に制御できる治具を提供することにより、実際の場面で起こっている重合挙動を再現して重合速度を測定できる方法を提供することにある。【解決手段】シャフトと、該シャフトの先端に同心円的に取り付けられたパラレルプレートの上皿と、パラレルプレートの下皿を有するレオメータ用の粘弾性測定用治具であって、該パラレルプレートの上皿が貫通孔を有する多孔質体であることを特徴とする、粘弾性測定用治具。【選択図】図２
