As the content of MAA in the terpolymers increases, their Tgs increase to be higher values than those predicted by the Fox equation. Moreover, the interfacial adhesion between PMMA and the terpolymers, evaluated from the cross cut tape test, also increases from 1B to 4B classification. The results show that the MAA units, introduced in order to induce a specific intermolecular interaction, effectively contribute to increase the interfacial adhesion with PMMA as well as the thermal stability of the resultant copolymers. 한국섬유공학회 고내열 POF용 클래딩 재료 제조(II) -Methacrylic Acid 공단량체 첨가 효과- Preparation of Cladding Polymers for Heat Resistant Plastic Optical Fiber (II) -Addition of Methacrylic Acid as Comonomer- Article 2 한국섬유공학회지, v.41, no.2, pp.86 - 90 한국섬유공학회지 41 2 86 90 kci ART000930480 plastic optical fiber cladding polymer methacrylic acid glass transition temperature plastic optical fiber cladding polymer methacrylic acid glass transition temperature
