  Abstract

The effects of glutaric acid and the lithium, sodium, potassium, magnesium, calcium, strontium, barium, zinc, and cadmium salts of glutaric acid on the formation of {beta}-crystalline form in isotactic polypropylene (iPP) at the crystallization temperatures 120 and 130°C have been investigated. It is found that glutaric acid and the sodium, potassium, and zinc salts of glutaric acid inhibit the formation of {beta}-crystalline form in polypropylene. Lithium glutarate has a limited positive effect on the formation of {beta}-crystalline form. Magnesium, calcium, strontium, barium salts of glutaric acid exhibit increased {beta}-nucleation abilities with the increasing atomic radii of the combined metals. Cadmium glutarate is a good {beta}-nucleating agent and the formation of {beta}-crystalline form is favored at the crystallization temperature of 120°C. The increases in the orientation of b-axes of the nucleated iPP samples are due to the presences of sodium and zinc salts of glutaric acid.
