겔 투과 크로마토그라피법에 의한 페 메타크릴산메칠수지와 스티렌계열수지화합물의 열분해 메카니즘에 관한 연구 = Mechanism of thermal degradation on waste poly methyl methacryate and styrene copolymer

다국어 초록 (Multilingual Abstract)

The mechanism of thermal degradation in blend of polymethyl methacrylate (PMIMA), styrene Copolymers such as (α-styrene-co-acrylonitrile) Copolymer(SAN), (acrylonitrile-butadiene-acrylonitri1e)terpolymer(ABS) were analyzed using the thermal analysis, gel permeation chromatography, pyrolysis gas chromatography and infra-red apectroscopy in the stream of nitrogen.
· It has been shown that the depolymerization of blends were a radical chain reaction and that degradation in the region of 300-400 C is associated with initiation by scission of the polymer at random along its length to from radicals.
· The dominant process in the degradation of PMMA-PS blend was main chain scission randomly due to weak link except PMMA-SAW and PMMA-ABS blend below 300 ℃ under nitrogen environment.
· The aimplest depolymerization reaction is that of PMMA from which monomer is obtained 90% over is PS, SAN and ABS blends.
