[en] New block copolymers of the ABA type, where B stands for polybutadiene (PBD) and A for polyglycidylmethacrylate(PGMA), poly(methylmethacrylate(MMA)-co-GMA) and PMMA-b-PGMA, respectively, have been successfully synthesized by using the diadduct of tert-butyllithium (tert-BuLi) to meta-diisopropenylbenzene (m-DIB) as a difunctional initiator. The PBD midblock has been synthesized in a cyclohexane/diethylether (100/6, v/v) mixture at room temperature, whereas the methacrylate outer blocks have been synthesized in a cyclohexane/diethylether/THF (100/6/150, v/v/v) mixture at -78°C. Block copolymers of a very narrow molecular weight distribution (1.10) have been analyzed by differential scanning calorimetry (DSC), transmission electron microscopy (TEM), and tensile testing. These materials are phase separated and can exhibit tensile strength up to 22 MPa together with very high elongation at break (1500%).

Funding text :
The authors are very much indebted to the IWT (Flemish Institute for the Promotion of Science-Technological Research in Industry) for the financial support of a joint research program with Raychem N.V. (Kessel-Lo, Belgium) and the Katholieke Universiteit Leuven (Prof. H. Berghmans and H. Reynaers). They warmly
thank Dr. N. Overbergh (Raychem, Kessel-Lo), Dr. Ph.Hammond, and Dr. J. Hudson (Raychem, Swindon) for stimulating discussions. They are grateful to the
‘‘Services Fédéraux des Affaires Scientifiques, Techniques et Culturelles’’ for general support in the frame of the ‘‘Pôles d’Attraction Interuniversitaires: Polymères.’’ Ph. Dubois is a research associate of the Belgian National Fund for Scientific Research (FNRS).
scite shows how a scientific paper has been cited by providing the context of the citation, a classification describing whether it supports, mentions, or contrasts the cited claim, and a label indicating in which section the citation was made.
