Use of 1,3-dioxacyclopentane as a solvent for polyester resins |
| 摘要 |
Polyester resins, comprising the polymerized residues of dibasic acids and diols, dibasic anhydrides and diols, and the lower alkyl esters of dibasic acids and diols, are soluble up to 40% by weight of solids in 1,3-dioxacyclopentane, and blends of 1,3-dioxacyclopentane with other relatively nontoxic solvents.
