Methylated siloxanes
WebUne catégorie de siloxanes (siloxanes méthyliques volatils) sont très utilisés pour produire des polymères à base de silicone ; pour leurs propriétés physico-chimiques dont : faible densité, masses molaires rapidement importantes, points d'ébullition assez élevés faible solubilité dans l'eau, faible viscosité, haute compressibilité, WebPolymers containing cyclic derivatives are a new class of macromolecular topologies with unique properties. Herein, we report the synthesis of a triblock copolymer containing a spirocyclic mid-block. To achieve this, a spirocyclic polystyrene (cPS) mid-block was first synthesized by atom transfer radical polymerization (ATRP) using a tetra-functional …
