Abstract
Resina de fenol, que puede obtenerse mediante la reacción de uno o varios fenoles no sustituidos o sustituidos con uno o varios aldehídos, caracterizada porque para la reacción se utiliza adicionalmente alquitrán de bisfenol A u otra mezcla de materiales preparada de otra forma, que contiene entre 10 y 50 % en peso de 4,4¿-bisfenol, entre 3 y 20 % en peso de 2,4¿- bisfenol, así como dímeros, trímeros y polímeros de bisfenol, estando caracterizada, además, porque puede obtenerse mediante la reacción en presencia de una sal metálica divalente como catalizador y una resina resol (resina de éter bencílico).
