Abstract
Hydroxyl group-containing triglyceride oils are effective nucleating agents for poly(ethylene terephthalate) and provide improved crystallization properties. The hydroxyl group-containing triglyceride oil may be combined with a conventional organic acid metal salt nucleating agent. By covalently bonding the hydroxyl group-containing triglyceride oil with a metal carboxylate, improved crystallization properties are obtained.
