Low ceiling temperature, thermodynamically unstable polymers have been troublesome to synthesize and keep stable during storage. In this study, stable poly(phthalaldehyde) has been synthesized with BF3-OEt2 catalyst. The role of BF3 in the polymeriza

Two routes to the thermal decomposition of poly(propylene carbonate) (PPC) have been considered-polymer chain-end unzipping and random chain scission. The inhibition and catalysis of each mechanism has been studied. End-capping of low molecular weigh

Research in microelectronics packaging has recently been driven by the reduction in size of the die the package contains. Die-die, interconnect-interconnect, and substrate-die distances are rapidly decreasing in size. As the electronic system shrinks
