Phenol-modified hydrocarbon resins with a high OH-number, method for the preparation thereof

摘要

Phenolic-modified hydrocarbon polymers with a high OH-number yet with excellent compatibility with non-polar solvents are suitable for preparing adhesives and coating materials. The polymers are obtained by isothermal, catalytic copolymerization of: 30-40% by weight phenolic compounds, 65-30% by weight aromatic, unsaturated hydrocarbons, and 5-30% by weight isobutene.
