초록

페녹시에틸아크릴레이트(PEA)-메틸메타크릴레이트(MMA)계와 PEA-메틸아크릴레이트(MA)계를 라디칼공중합하였고, 얻어진 공중합체의 조성을 핵자기공명스펙트럼으로 분석하였다. 구한 조성으로 부터 단량체반응성비 및 PEA에 대한 Alfrey-Price 식의 Q-e값을 다음과 같이 결정하였다. PEA(1)-MMA(2) : r₁=0.20, r₂= 1.95, Q₁=0.59, e_l=1.38 ; PEA(1)-MA(2) : r_l= 1.05, r₂=0.92, Q₁=0.55, e_l=0.83. 또 이들 공중합체의 점도와 열적성질을 측정하였고 그 결과는 다음과 같았다. 이들 공중합체의 inherent viscosity와 유리전위온도(T_g)는 PEA의 함유율이 증가할수록 떨어졌다. PEA-MMA공중합체의 열분해온도(T_d)는 PEA의 함유율이 증가할수록 상승하였으나 PEA-MA공중합체의 T_d는 PEA의 함량이 변하더라도 거의 변하지 않았다.

Phenoxyethylacrylate(PEA) was radically copolymerized with methylmethacrylate(MMA) and methylacrylate(MA) in dimethylformamide at 60℃, respectively. The compositions of the copolymers were analyzed by nmr spectroscopy. The monomer reactivity ratios for the copolymerizations of the two systems and Alfrey-Price''s Q and e values for PEA were determined as follows : PEA(1)-MMA(2) : r₁=0.20, r₂=1.95, Q₁=0.59, e_l=1.38, PEA(1)-MA(2) ; r_l=1.05, r₂=0.92, Q₁=0.55, e₁=0.83. Also, the viscosity and thermal properties of the copolymers were measured. The inherent viscosity and the glass transition temperature were decreased with increasing PEA content in the copolymers, and the heat decomposition temperature was scarcely varied with increasing PEA content in PEA-MA copolymer, but increased in PEA-MMA copolymer.
