The present invention relates to modifiable linear polyunsaturated polymers and processes for preparing the same comprising reacting solely at least one bifunctional nucleophilic compound with at least one α-functional unsaturated monomer. The at least one bifunctional nucleophilic compound of the invention comprises two nucleophiles independently selected from the group consisting of C, N, O, S and Se. The at least one α-functional unsaturated monomer of the invention comprises two leaving groups L
1
and L
2
, wherein at least one of the leaving groups L
1
and L
2
of the at least one α-functional unsaturated monomer is part of the nonaromatic unsaturated structure C═C—C
α
-L. The double bond of said α-functional unsaturated monomer is maintained in the polyunsaturated polymer.
