PIB-Phenol

Poly(isobutylen)-Phenol. Hydroxy terminated. Used as educt for further reactions to blockcopolymers and/or fuel additive.

Polyisobutenylphenols are obtained by alkylation of an aromatic hydroxy compound with essentially homopolymeric polyisobutenes in the presence of a Lewis acidic alkylation catalyst. 

Polyisobutenylphenol is an important starting product for the production of fuel detergents and is itself used as a fuel additive. It is advantageous if the phenol is essentially monoalkylated and/or substituted in the para position.

Poly(isobutylene) (PIB)-Phenol serves as a viable precursor in the synthesis of diblock copolymers. Specifically, when PIB-Phenol with an approximate molecular weight of 2300 g/mol is employed in a reaction that includes a suitable catalyst and ethylene oxide, the resulting product is the corresponding poly(isobutylene)-b-poly(ethylene oxide) diblock copolymer. An exemplar of this is PIB-PEO 2300, which is commercially available alongside other diblock copolymers on our website.
