EPOXY RESIN COMPOSITION CONTAINING ISOCYANURATES FOR USE IN ELECTRICAL LAMINATES

A resin composition comprising oligomers having a molar ratio of isocyanurate to oxazolidinone greater than 1 :1, wherein the weight average molecular weight of the oligomers is less than or equal to 3000, as measured by gel permeation chromatography. Such resin compositions may be combined with a h...

More Information
Summary:A resin composition comprising oligomers having a molar ratio of isocyanurate to oxazolidinone greater than 1 :1, wherein the weight average molecular weight of the oligomers is less than or equal to 3000, as measured by gel permeation chromatography. Such resin compositions may be combined with a hardener to form a curable composition. Also disclosed is a process for forming a resin composition, including: reacting diisocyanates to form isocyanurates; reacting isocyanate groups in the isocyanurates and unreacted diisocyanates with an epoxy precursor to form a resin composition comprising oligomers having: a molar ratio of isocyanurate to oxazolidinone greater than 1 :1; wherein the weight average molecular weight of the oligomers is less than or equal to 3000, as measured by gel permeation chromatography. Such compositions may be useful in prepregs and laminates.
