“…The monomers that are susceptible to anionic polymerization are those that can form stable carbanionic species under polymerization conditions. The most studied monomers are styrenic, dienic, and also cyclic that can react with nucleophiles leading to ring opening 1, 2, 14, 15. The double bond must have substituents that can stabilize the negative charge, by charge withdrawing making the anions stable to possible nucleophilic attack from other species.…”

“…The range of the basic properties available from a family of monomers depends essentially on the ability to orient them to well-defined macromolecular characteristics. The possibility of designing optimal material properties by using the appropriate graft or block structures suggests a tremendous commercial potential and both block and graft copolymers have achieved considerable industrial importance 1) . Functional polymers are of interest for the synthesis of block and graft copolymers, model networks and interpenetrating networks which are appreciated for their original properties in relation to either a well defined molecular structure or a particular multiphase morphology [2][3][4] .…”

“…Nevertheless, the chain ends can be quantitatively neutralized by using an excess of tetravalent metal alkoxide, e.g., one metal per chain end or two metals per linear chain (eq 1). The association of the chain ends into multi--COOH + Ti(OR)4 -~*COO-Ti(OR)3 + ROH (1) I 21 + H20 --C00-Ti(0R)2-0-Ti(0R)2-00C-+ 2ROH (2) II nX + mXX + xHzO --iji oxo hydroxides;--OOCwv. )^^+ /ROH (3) / 3/?…”

“…As tetravalent metal-carboxylate bonds are essentially covalent, they are practically insensitive toward water and alcohol, which explains the synthesis of representative halato-telechelic polymers through the pathway described by eq 1-3. In conclusion, the neutralization of , -dicarboxylic acid polymers by an excess of tetravalent metal alkoxides is quite attractive because thermoreversibly cross-linked polymers are prepared without bothering about avoiding water, which in fact is now a required reagent, and without necessarily removing the alcohol formed as the reaction subproduct (eq [1][2][3].…”
