    摘要： Novel isocyanato-azetidinedione compounds are provided which have the formula ##STR1## wherein R and R.sub.1 can independently selected from hydrogen and hydrocarbyl or can be joined together and along with the carbon to which they are attached represent a cycloalkane residue having 4 to 6 ring carbon atoms, y is an integer from 1 to 7 and X is a hydrocarbon radical having a valency of y plus one.The monoisocyanate compounds are used as intermediates to provide further novel azetidinedione containing derivatives in the form of azetidinedione-isocyanurates (II) and azetidinedione-urethanes (III).All three classes of compounds can be employed as acid scavenging agents for stablizing various kinds of halogenated polymer systems. Notably, (I) and (III) form highly useful polyamide-polyureas and polyamide-polyurethanes respectively by reaction with organic polyamines.

    摘要： 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.
