During the development of a palladiumcatalyzed C–H activation cross-coupling reaction involving acyl halides, it was noted that palladium(II) acetate catalyzes the acylative cleavage of tetrahydrofuran (used as a solvent) at room temperature to afford the corresponding 4-chlorobutyl ester derivative. After optimization, the reaction was shown to work well with epoxides, oxetane and tetrahydrofuran

A highly elastic polyvinyl chloride composition comprises polyvinyl chloride-rubber particles including rubber particles and secondary polyvinyl chloride particles formed by combination of primary polyvinyl chloride particles. In the polyvinyl chloride-rubber particles, pores between primary polyvinyl chloride particles that form secondary polyvinyl chloride particles are filled with rubber particles. A film manufactured using the polyvinyl chloride composition has high elasticity, and rubber particles contained in the film have high uniformity. In addition, by using cross-linked rubber particles, the polyvinyl chloride composition may show high elongation, large tensile strength, and excellent processability due to no increase in viscosity even when the content of plasticizer used is not increased during a film formation process.
