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

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.

BROMINATION OF ORGANIC ALLYLIC COMPOUNDS BY USING <i>N</i>,<i>N′</i>-DIBROMO-<i>N</i>,<i>N′-</i>1,2-ETHANE DIYL <i>BIS</i>(2,5-DIMETHYL BENZENE SULPHONYL)AMINE
ABSTRACT N,N′-Dibromo-N,N′-1,2-ethane diyl bis(2,5-dimethyl benzene sulphonyl)amine is an efficient brominating agent for bromination of allylic positions of different organic compounds. This reagent in presence of benzoyl peroxide can brominates the allylic positions of organic compounds in ambient conditions in carbon tetrachloride.
