Abstract
We first synthesized N-phenylcyclotrisiloxazane (D3^(NPh)) through a cyclization of α,ω- dichlorohexamethyltrisiloxane 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 methacrylate 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.

α,ω-Dichlorohexamethyltrisiloxane의 aniline과 고리 반응으로부터 N-phenylcyclotrisiloxazane(D3 ^(NPh))을 합성하고 이를 hexamethylcyclotrisiloxane(D3)과 이온 공중합시켜 poly(dimethylsiloxane-co-N-phenylsiloxazane)공중합체(PDMS-NPSOX)를 제조하였다. 이를 chloroethyl methacryalte에 도입하여 PDMS-NPSOX unit가 도입된 아크릴 단량체를 제조하였으며, 이를 MMA 및 n-butyl acrylate와 공중합시켜 PDMS-NPSOX가 도입된 삼원 아크릴 공중합체를 제조하고, 그 특성을 조사하였다. 단량체 조성은 생성 공중합체의 Tg가 25 ℃가 되도록 선택하여 공중합시켰다. 공중합체에서 PDMS만 도입된 경우 Tg 가 20 ℃인데 비하여 PDMS-NPSOX unit이 도입됨에 따라 25 ℃로 증가되었으며 접착력도 1.76 N/cm에서 2.23 N/cm로 증가되었다.
