Patent ID: 7074858

Claim:
A step-growth addition curable oligomer composition comprising: a) a first component oligomer, having a carbon-carbon backbone, and a degree of polymerization <300, comprising a plurality of polymerized monomer units comprising pendant reactive nucleophilic or electrophilic functional groups; and b) a second component oligomer having a carbon-carbon backbone, and a degree of polymerization <300, comprising a plurality of polymerized monomer units comprising pendant functional groups co-reactive with said pendant reactive nucleophilic or electrophilic functional groups of said first component oligomer; wherein at least one of a) and b) has a functionality of greater than 2, wherein a) and b) are capable of forming a cured composition by a condensation or a displacement reaction between said nucleophilic and electrophilic functional groups, and wherein the composition is melt-processible at temperatures of 100Â° C. or less, and has a residual content of less than 2 weight %.
