Monomers for double ring-opening polymerization with expansion
摘要:
A method of preparing a polymerizate from a reactant monomer of prepolymer which undergoes shrinkage during the formation of said polymerizate which comprises reacting said reactant monomer or prepolymer in the presence of a monomer selected from the group consisting of: ##STR1## wherein R.sub.1 -R.sub.8 are as defined herein to form a polymerizate containgin said reactant monomer or prepolymer as chemically contained constituents thereof, and resinous compositions and composites as well as polymers polymerized from such monomers or prepolymers.
