9 . The composition of claim 1 , comprising a modulus between about 0.5 GPa and about 3.0 GPa.

10 . The composition of claim 1 , comprising an elongation at break between about 0.1% and about 100%.

11 . The composition of claim 1 , comprising a glass transition temperature between about 0° C. and about 250° C.

12 . A method comprising:
reacting a first functionalized intermediate with a second functionalized intermediate to form a product, wherein:

the first functionalized intermediate comprises

the second functionalized intermediate comprises
the product comprises,

R comprises a reactive end group,
R 1 comprises a first bridging group,
1≤x≤100, and
1≤y≤100.

13 . The method of claim 12 , further comprising:
prior to the reacting, in a first mixture comprising a deconstruction product and a functionalized reactant, functionalizing the deconstruction product, wherein: the deconstruction product comprises
