  • Patent number: 6861099
    Abstract: A phenol-formaldehyde resole resin is combined with an ammonia-based formaldehyde scavenger to produce a product useful, for example, as a binder used in the production of glass fiber insulation products. The starting resin may have a free formaldehyde content of 1.5 to 14 wt. %, based on a total weight of the resin, and the resin and scavenger may be combined at a molar ratio in the range of 0.1 to 5. The resulting binder may have a free formaldehyde content of 1 wt. % or less, based on a total weight of the reaction product. This binder may then be applied to a glass fiber base material in a conventional manner.
    Type: Grant

  • Publication number: 20040131874
    Abstract: A binder composition based on phenol-formaldehyde resin for making fiberglass insulation and related fiberglass products (glass fiber products) and containing a copper or vanadium odor-eliminating agent, such as cupric chloride, that when cured exhibits a lower amount of odor caused by the presence of trimethylamine.

  • Patent number: 6399740
    Abstract: Phenol aralkyistion polymers can be prepared by reaction among a phenolic monomer, at least one styrenic monomer and an aryl diolefin. A phenolic monomer can be initially aralkylated in the presence of an acid catalyst with a first portion of at least one styrenic monomer to obtain an aralkylated phenol. The aralkylated phenol thereafter can be reacted with an aryl diolefin to obtain a phenol aralkylation polymer. Optionally, (though preferably) the phenol aralkylation polymer is further aralkylated with a second portion of at least one styrenic monomer. By employing specific catalyst concentrations, reactant concentrations, reaction temperatures, and reaction times, the formation of mono-functional and non-functional by-products is substantially reduced.
