This article describes the thermal degradation behavior of polycarbonate-polydimethylsiloxane (PC-PDMS) block copolymer with dimethylsiloxane (DMS) block size 15 to 350 units, and the effects of the PDMS block size and the PDMS content on thermal degradation were studied. PC-PDMS block copolymer with DMS unit of 100 had the lowest value of maximum weight loss rate and the most residue containing silica in the other PC-PDMS block copolymers. The PDMS block size influenced PDMS dispersibility in PC and the moderate PDMS dispersion ( 50 nm) caused high flame retardancy for PC. The control of nanodispersion of PDMS caused the change of thermal degradation behavior and high flame retardancy in PC.

“…Beach et al showed that the incorporation of 25 weight percent PDMS blocks into PC reduced the ductile brittle transition temperature from −20°C to −110°C. In addition, Okamoto showed that glass‐filled composites based a PC‐PDMS multiblock copolymer matrix can provide higher impact strength and lower melt viscosity than glass‐filled PC. Further, Nodera and Kanai showed that the incorporation of PDMS into PC via block copolymerization enhances flame retardancy even at PDMS contents as low as 1.0 wt%.…”

An array of perfectly alternating polycarbonate‐polydimethylsiloxane (PC‐PDMS) multiblock copolymers possessing systematic variations in block molecular weights were successfully produced by coupling preformed PC and PDMS telechelic oligomers using hydrosilylation. Based on gel permeation chromatography results, the multiblock copolymers were essentially void of the oligomeric precursors. Despite the relatively large difference in solubility parameter between PC and PDMS, the multiblock copolymers exhibited significant partial miscibility between the two phases. As expected, the degree of partial miscibility was dependent on the molecular weight of the blocks with the extent of partial miscibility increasing with decreasing block molecular weights. Morphological characterization using small angle X‐ray scattering showed that, at a given PC block molecular weight, the uniformity of the two phase morphology increased with increasing PDMS block molecular weight, which is consistent with a decrease in the extent of phase mixing with increasing PDMS block molecular weight.

“…He has adopted the firstorder shear deformation theory and tensor polynomial failure criteria. Okamoto has investigated the impact resistance of glass fiber reinforced PC using polydimethylsiloxane (PDMS) block copolymer [10]. Very recently, the hydrolytic stability of PC/GF composites has been reported by Jancar [11].…”

A series of polycarbonate (PC), reinforced with short glass fiber (SGF) in different weight ratios viz., 10, 20 and 30%, has been fabricated by melt mixing with the aid of a twin screw extruder, in order to study the influence of glass fiber reinforcement on PC. The test specimens were fabricated as per ASTM standards and evaluated for their physico-mechanical properties. Incorporation of short glass fiber to PC enhances the tensile behavior of the composites significantly. The morphological behavior of PC composites has been performed using a scanning electron microscope (SEM). The experimentally measured tensile results were used to estimate the stress distribution in the bearing component, made of glass fiber reinforced polycarbonate (GFR-PC) composite, using three-dimensional finite element analysis (FEA).
