Participants

Conditions

Temperature: 180 °C

Procedure

Into the resin cook apparatus described in Example 1 are charged dimethyl adipate (200 grams, 1.15 moles), BHDP (302 grams, 1.37 moles), and dibutyltin oxide (1.0 gram). The mixture is heated at 180° C. for 4 hours. A conversion of 93 percent is obtained based upon the methanol taken overhead. The tacky polyester has an average molecular weight of 1,974, an acid number of 2.4, and a hydroxyl number of 50.0.
