EP-302 → Dimethyl Phthalate

Participants

Reaction Steps

Epikote 1004 (180 g), a homopolymer of butylene terephthalate (120 g) and triphenylethyl phosphonium iodide (0.3 g) were melt blended in an extruder as described in Composition 1. A sample of the solidified resulting mixture (30 g) and dimethylphthalate (10 g) were heated in a beaker to 260° C. and poured into butyl diglycol acetate (120 g) at 125° C. The mixture was dispersed using a Silverson high speed stirrer for 3 minutes during which time the temperature rose to 140° C. The mixture was cooled using an ice bath, reaching 49° C. within one minute. The resulting dispersion had a non-volatile content of 18.7% and a particle size range of 0.5 to 10μ.
