CYANATE-BASED RESINS WITH REDUCED VISCOSITY AND DUROMERS PRODUCED THEREFROM WITH IMPROVED IMPACT RESISTANCE

摘要

The invention relates to a cyanate resin that can be obtained by mixing at least
(i) one difunctional, oligofunctional and/or polyfunctional cyanate and/or of at least one prepolymer thereof, optionally in combination with at least one additional copolymerizable component and(ii) at least one siloxane and/or a siloxane-containing compound, characterized in that said resin contains a linear polydialkylsiloxane with a viscosity ranging from 500 to 1500 and/or a polydialkylsiloxane caprolactone or caprolactam copolymer as siloxane and/or siloxane-containing compound.;The invention further relates to a substrate that is saturated or coated with said type of cyanate resin, and a duromer that can be obtained by compressing and/or heating the cyanate resin or the saturated or coated substrate.
