15246 IUPAC Gold Book - coumarone-indene polymer 10.1351/goldbook.15246 15246 current synonym: 1-benzofuran-indene polymer 1 Polymer prepared from a mixture containing 1-benzofuran (formerly coumarone) and indene. A mixture of coal-tar and gas-tar distillates is commonly used to prepare a coumaroneindene polymer. A coumarone-indene polymer contains structural units such as: Coumarone-indene polymers are film-forming materials. Coumarone-indene polymers are sometimes, particularly in a public (popular) use and technological practice, called coumarone resins or coumarone-indene resins. Use of these terms is discouraged.
