Claim 2
Dependent Claim
44 words
A thermosetting polymeric composition prepared by effecting the step-growth polymerization reaction in the melt phase of a first reactant consisting of an oligomer containing a plurality of aromatic hydroxyl groups and a second reactant consisting of a compound having at least two 2-oxazoline groups.
Claim 3
Dependent Claim
16 words
The polymeric composition according to claim 1 wherein said first reactant is a phenol/aldehyde oligomeric condensate.
Claim 4
Dependent Claim
