Popis:	We first synthesized N-phenylcyclotrisiloxazane (D3 NPh ) through a cyclization of α,ω- dichloro- hexamethyltrisiloxane with aniline and prepared poly(dimethylsiloxane-co-N-phenylsiloxazane) copolymer (PDMS-NPSOX) by a ring opening copolymerization of them with hexamethylcyclotrisiloxane (D3). An acrylate monomer modified with PDMS-NPSOX was synthesized by using chloroethyl meth- acrylate and copolymerized with methylmethacrylate (MMA) and n-butylacrylate. The composition of the copolymer was chosen to control their glass transition temperature (Tg) to 25 ℃. By changing the comonomer from PDMS to PDMS-NPSOX, Tg and adhesive strength of the copolymer were increased from 20 to 25 ℃ and from 1.76 to 2.23 N/cm, respectively.
