What does SPS stand for?

Recently, our group has reported 3DOM syndiotactic polystyrene (3DOM sPS) materials with pore diameter 80 ~ 800 nm by coordination polymerization (17-19), which possess some excellent properties, such as high melting temperature, fast crystallization rate, low dielectric constant, low permeability resistance to gas, and good chemical resistance because of the semicrystallinity (20).

The plant will manufacture functional resin compounds by mixing such materials as glass fibers into polycarbonate, syndiotactic polystyrene and other petrochemical resins made at its plant in Chiba Prefecture, eastern Japan.

Tokyo, has resumed full-scale production of syndiotactic polystyrene (SPS) resin at its 11-million-lb/yr Chiba plant in Japan.

The plant will manufacture functional resin compounds by mixing such materials as glass fibers into polycarbonate, syndiotactic polystyrene and other petrochemical resins made at its plant in Chiba Prefecture, eastern Japan.

INTRODUCTION In the last years, syndiotactic polystyrene (sPS) has received considerable attention because of its high melting temperature, fast crystallization rate, low dielectric constant, and good chemical resistance.

of Japan has started to manufacture and sell syndiotactic polystyrene (SPS) compounds in North America.

The most noteworthy recent product development was the introduction of Questra(TM), a syndiotactic polystyrene by Dow Chemical in 1995.

On the one hand, many researchers have focused their work on blends of syndiotactic polystyrene (sPS) with other polymers [4-7], due to the very promising properties of this polymer, and especially because of its crystalline polymorphism and its relatively fast crystallization rate.
