| 摘要 |
A thermoplastic resin composition which comprises a polyethylene glycol compound such as polyethylene glycol and a water soluble thermoplastic polymer compound compatible with said polyethylene glycol compound such as a polymer comprising in a side chain a tertiary nitrogen atom such as of a lactam structure such as pyrrolidone and caprolactam, a tertiary amino group and a quaternary ammonium group. This resin composition softens at a relatively low temperature and is soluble in water, and besides adheres to various materials. Thus it is particularly useful as an adhesive which can temporarily bond an article to be processed to a jig at a low temperature and can be washed off with water to remove it from the article after the processing. |
