Title: Rigid, low softening-point terpene resins - for various industrial applications
IPC: C08G61/02
Filed: 1974-12-06
Abstract: The specification describes the synthesis of terpene resins with softening points between O and 85 degrees C by reaction of a terpene with a cyclic monoterpene oligomer in the presence of a catalyst.
