Synthesis of graft copolymers of siloxanes with pivalolactone, γ and δ-valerolactones and ε-caprolactam will be described. A carboxyl functionalized siloxane, previously prepared, promotes ring opening polymerization of the corresponding lactone or lactam, under conditions depending of the ring size, producing the graft copolymers. Products were characterized by spectroscopy, GPC, DSC, TGA. Surface composition was studied by XPS and water contact angle.
