Abstract
A series of interpenetrating polymer networks(IPNs) composed of hydrophilic polyurethane(PU) and hydrophobic polystyrene(PS) were prepared by a sequential polymerization. One series was prepared with varying the composition of N-MDEA(N-methyldiethanolamine) in PU network, the oether with varying the amount of PEO side chains. The series of PU/PS IPN, PEO-grafted PU/PS IPN were ionized by quaternizing the tertiary amine of N-MDEA with γ-propane sultone. Their physical, thermal and mechanical properties were examined by a number of different techniques. The PU/PS IPNs all exhibited microphase separated structures with dispersed PS domains in the continuous PU matrix. The PS domain size decreased with increasing the amount of N-MDEA in PU and increasing the amount of P대 side chains in PU. PU/PS IPNs exhibited two transition temperatures, nated PU/PS IPNs with ionic sulfonate group were more hydrophilic than the corresponding nonionized materials. PU/PS IPNs showed excellent mechanical properties compared to PU and PS homopolymers.

PU 가교구조에 3급 아민 N-MDEA (N-methyl diethanolamine)를 사슬 연장제로 사용한 폴리우레탄(PU)/폴리스티렌(PS) IPN과 N-MDEA를 포함한 PEO 곁사슬을 그라프팅시킨 PU/PS IPN을 합성한 다음, 폴리우레탄 가교구조에 있는 3급 아민 N-MDEA를 γ-propane sultone과 반응시켜 4급화 하여 술폰이온을 zwitterionomer 형태로 도입하여, 술포화 PU/PS IPN과 슬폰화 PEO-grafted PU/PS IPN을 합성하였다. 그리고 이들 재료의 물리적, 열적, 기계적 특성을 알아 보았다. 모든 PU/PS IPN은 친수성 PU 연속상에 소수성 PS가 분산된 미세상분리 구조를 가지고 있으며, 사슬 연장제로 사용된 M-MDEA양의 증가, 그라프트된 PEO 곁사슬의 증가에 따라 상분리 억제로 인해 각 상의 혼화성이 증가하여 소수성 분산상의 크기가 감소하였다. 그리고 ammmonium sulfonationqksdmd에 의해 술폰 이온기가 도입되면 재료의 친수성이 상당히 증가하고 물과의 계면 에너지도 감소하였다. PU/PS IPN의 기계
