摘要:

The tensile properties of hydroxypropylcellulose sheets which were formed by means of hot compression at temperatures between 150° and 220°C were examined at room temperature. The marked increase of elongation at breaking and the decrease of the Young's modulus over temperatures of 210°C agreed well with the phase transition observed by the polarized light microscope. These phenomena have been explained by X‐ray and SEM studies.
