CA 2322279

Novel polyindanebisphenols or PIBPs for the preparation of new and improved thermosetting polymers having general formula (I) are provided. Also disclosed are thermoplastic or thermoset compositions prepared using the novel compounds of the invention, as well as methods of making and using the same. When copolymerized or reactive with other commercial resins such as, e.g., epoxy compounds, PIBP based polymers are characterized by high glass transition temperature ("Tg"), low dielectric constant, low moisture absorption, low coefficient of expansion, low cost, and can be processed on equipment typically used for the production of epoxy based laminates.

L'invention concerne de nouveaux polyindanebisphénols ou PIBP destinés à la préparation de nouveaux polymères thermodurcissables améliorés de la formule générale (I). L'invention concerne également des compositions thermoplastiques ou thermodurcies préparées par utilisation des nouveaux composés selon l'invention, ainsi que leurs procédés de préparation et d'utilisation. Lorsqu'ils sont copolymérisés ou mis en réaction avec d'autres résines commerciales telles que, par exemple, des composés époxydiques, les polymères à base de PIBP se caractérisent par une température de transition vitreuse ("Tg") améliorée, une faible constante diélectrique, une faible absorption de l'humidité, un coefficient d'expansion faible, un faible coût, et on peut les traiter sur du matériel utilisé en général pour produire des stratifiés à base d'époxyde.
