A practical method was developed to characterize and to quantify the content of filler and binder in polymer bonded explosive (PBX) by thermal and spectroscopic analysis. Energy materials, research development explosive (RDX), high melting explosive (HMX), aluminum, and an inactive Dechlorane were used as fillers, and polyvinylacetate and plasticizer diethyl-hexyl adipate (DEHA) were used as binders. The concentrated suspensions were mixed in a batch melt mixer and analyzed by TGA, ATR-IR and NMR for quantification. The contents obtained from this new method corresponded well with the prototype contents. It was thought that this method could be applied to determine the contents of fillers and binders in PBX faster and more easily than the traditional methods.

고분자 복합화약 및 그 모사체의 열적, 분광학적 분석을 통해 충전제와 결합제의 함량을 결정하는 실용적인 방법을 개발하였다. 충전제로는 에너지 물질인 research development explosive(RDX), high melting explosive (HMX), 알루미늄 및 비활성인 Dechlorane을 사용하였으며 결합제로는 폴리비닐아세테이트와 가소제인 diethyl-hexyl adipate(DEHA)를 사용하였다. 회분식 용융 혼련기를 사용하여 농축 현탁계를 혼련하였고 TGA, ATR-IR, NMR을 이용하여 충전제와 결합제의 함량을 조사하였다. 분석 결과 실제 함량과 잘 부합하는 바 고분자 복합화약의 분석에 통상적으로 사용하는 방법보다 빠르고 간편하게 응용이 가능하리라 판단된다.
