Poly(dicyclopentadiene-co-p-cresol)

Poly(dicyclopentadiene-co-p-cresol) (CAS 68610-51-5), commercially known as IONOL LC, is a phenolic resin produced by reacting p-cresol with dicyclopentadiene and isobutylene. It functions as a reactive modifier and antioxidant stabilizer in polymer and elastomer systems, where controlled crosslinking and processing stability are the primary requirements.

In rubber compounding and tire manufacturing, it acts as a tackifier and crosslinking agent that improves green strength and bond integrity before vulcanization. Coating formulators incorporate it to enhance oxidative stability and adhesion in high-performance industrial finishes. In adhesive and sealant systems, it contributes to cohesive strength.

It provides thermal resistance, particularly in hot-melt and pressure-sensitive formulations. Plastics processors use it as a stabilizing resin component where long-term thermal aging performance is critical. This material is essential for meeting end-product specification compliance. Poly(dicyclopentadiene-co-p-cresol) is supplied as a solid resin, typically in flake or granule form.

This form facilitates handling and dosing in industrial processes. Technical grade is the standard commercial specification for rubber, coatings, and adhesive applications. Packaging is generally available in multi-kilogram bags or drums suited to bulk industrial procurement. This ensures efficient transport and storage for large-scale manufacturing operations.
