US 12,012,487 B2 · In-situ alkylphenol-aldehyde resins

Abstract

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.

An in-situ process for preparing an alkylphenol-aldehyde resin, comprising:

providing an alkylphenol composition comprising:
a butylphenol composition comprising one or more butylphenol compounds, each compound having one or more butyl substituents;
and an octylphenol composition comprising one or more octylphenol compounds, each compound having one or more octyl substituents, wherein at least one of the butylphenol composition and the octylphenol composition is a raw alkylphenol composition;
about 7 to about 14 wt % di-tert-alkylphenol;
and
at least about 1 wt % phenol;
