概要
- 論文の詳細を見る
Measurements of density and ultrasonic velocity have been performed in dilute benzene solutions of methyl methacrylate of different polymerization stages, including the monomer and the final product of polymerization. The apparent molal volume and the apparent molal compressibility have been computed from the experimental results. The amount of polymerization (the ratio of reacted monomers to initial ones) of each intermediate product has been estimated from the molal properties respectively, taking account of the fact that these molal properties of polymer with high polymerization degree are independent of polymerization degree. The values of the amount of polymerization, estimated from each of the molal properties, are in satisfactory agreement with each other and also with the value computed from the ultrasonic absorption in the previous paper.
