摘要:
The invention relates to an in-situ process for preparing an alkylphenol-aldehyde resin. The process comprises the step of providing a raw alkylphenol composition. The raw alkylphenol composition comprises one or more alkylphenol compounds and at least about 1 wt % phenol. Each alkylphenol compound has one or more alkyl substituents. The raw alkylphenol composition is reacted directly, without pre-purification, with one or more aldehydes to form an in-situ alkylphenol-aldehyde resin. The invention also relates to an in-situ alkylphenol-aldehyde resin formed from the in-situ process, and its use in a tackifier composition and rubber composition. The tackifier composition and rubber composition containing the in-situ alkylphenol-aldehyde resin show, inter alia, improved tack performance.

摘要:
This invention relates to a process for stabilizing a phenolic resin containing a mixture of linear phenolic resins and calixarenes and a demulsifier composition comprising the stabilized phenolic resins prepared from the process. The process comprises contacting the phenolic resin with an alkylene carbonate, in the presence of a base catalyst, to at least partially alkoxylate the phenolic hydroxyl groups of the calixarenes. This process forms a stabilized phenolic resin with an increased solubility in a hydrocarbon solvent.
