た。2. Description of the Related Art Polyketone resins composed of carbon monoxide and one or more unsaturated compounds have high resistance to solvents, chemicals, and the like.
Due to its excellent heat resistance, sliding properties, and barrier properties, various applications are being studied. However, such a polyketone-based resin has many carbonyl groups in the molecular chain, so it deteriorates in the molten state during the molding process, causing a gel due to coloring of the molded product and an increase in viscosity over time, and finally the molding process. There was a problem that it became impossible to do.

観が不良となることがわかる。From Table 1, it can be seen that, when a sheet was formed using the composition obtained by mixing the polyketone resin of Example 1 with a fluoropolymer, the formation of a crosslinked gel was suppressed and the composition was stable over time. Comparative Example 2 in which a sheet was formed with only a commercially available polyketone resin while a sheet was obtained with thickness accuracy
It can be seen that a crosslinked gel is easily generated, and that the resin stagnates in the die, so that the flow of the resin is deteriorated and the thickness accuracy and appearance are poor.
