Vernetzbare Polyester/Isocyanat-Zusammensetzungen zur Herstellung von Verbundstoffen
摘要
Disclosed are crosslinkable polymeric compositions which show a low content of vinyl monomers, are suitable for the fabrication of composite materials having good mechanical properties and comprise: (A) a liquid polyisocyanate; (B) a polyol having a maximum functionality of 7 and an average molecular weight of from about 200 to about 10,000; (C) a vinylester resin or unsaturated polyester resin; (D) a radical polymerization initiator stable at temperatures below 70 DEG C; (E) a decomposition promoter for the initiator (D); (F) a trimerization catalyst for the isocyanate (A); (G) optionally, a mineral filler having dehydrating properties. l
