ABSTRACT:
A novel class of unsaturated polycyclic ethers and esters comprises unsaturated ether and ester derivatives of a hydroxyaryl-substituted [4.4] spirodilactams having nitrogen atoms in the 1- and 6-positions of the spiro ring system and having the hydroxyaryl groups attached to each spiro ring nitrogen. Such unsaturated ethers and esters react with conventional curing agents to produce cured, insoluble products having high glass transition temperatures.
