Today, the coumarone— indene resins are obtained using a BF3 / phenol
mixture as initiator (see below). The polymerization process of coal tar and
petroleum fraction (from which aromatic hydrocarbon resins are obtained) are
similar.
COUMARONE-INDENE RESINS Fractionation of coal tar naphtha (b.p. 150-200°
C) yields a portion boiling at 168-172°C consisting mainly of coumarone (
benzofuran) and indene (Figure 17.5). The products bear a strong formal
resemblance ...

Pressure-Sensitive Formulation
The polymerisation of coumarone oil ( with a boiling point of 150-200°C ) leads to
coumaro- ne resins. Such oils contain indene, coumarone, styrene,
methylstyrene, methylindene and methylcoumarone. Coumarone-indene resins
are aromatic ...

Technology of Pressure-Sensitive Adhesives and Products
It is important to avoid a long storage time of the feedstock because oxidation
processes can be easily produced, affecting the polymerization reaction and the
color of the coumarone–indene resins. Coumarone–indene resins were
produced ...
