| titleOfInvention | Molecular weight fractionation of ladder-type silicone resin |
| abstract | PURPOSE: To carry out the titled fractionation in high reproducibility, by dissolving a silylated silsesquioxane polymer in a solvent having the maximum average molecular weight to be fractionated as the limit of soluble molecular weight, and precipitating the polymer from the solution by the addition of a solvent having the minimum average molecular weight to be fractionated as the limit of soluble molecular weight. n CONSTITUTION: For example, a component having a molecular weight of 1W5×10 4 is fractionated from a silylated silsesquioxane polymer (e.g. polymethyl silsesquioxane), by dissolving the component having a weight-average molecular weight (Mw) of ≤5×10 4 in a solvent having the maximum average molecular weight to be fractionated as the limit of soluble molecular weight (e.g. isopropanol), removing the insoluble component, adding a solvent having the minimum average molecular weight to be fractionated as the limit of soluble molecular weight (e.g. methanol) to effect the precipitation of the component having Mw of >1×10 4 , and recovering the precipitate. n EFFECT: The obtained resin has excellent sharpness and sensitivity when used as an electron beam resist. n COPYRIGHT: (C)1986,JPO&Japio |
