Plastics wastes used as aggregate of the mortar are expanded polystyrene (PS) and expanded ethylene-vinyl acetate copolymer (EVAc). Expanded PS is obtained from packing materials wastes and so on. Now, about 9,200 tons of expanded PS have been crushed and used as lightweight aggregate for plastering materials every year in Japan. EVAc chip is found in cushion materials for shoes etc. These plastics wastes are crushed and graded for the purpose. This mortar was developed about 20 years ago. The suitable application of this mortar has been discussed and studied until now. [Pg.62]

In 1976, Langer and Folkman published a landmark paper in which several polymer systems were studied with respect to biocompatibility and sustained release of macromolecules. Ultimately, they determined that two of the polymer systems were most biocompatible. Pellets made from casting of ethylene-vinyl acetate copolymer (EVAC) showed no significant inflammation after implantation as did the pellets cast of Hydron, a polymer of hydrox-yethylmethacrylate. In terms of in vitro release kinetics, while both polymer systems exhibit a significant initial release (i.e., "burst kinetics"), the ethylene-vinyl acetate system had a slower overall release profile that persisted significantly longer, making it more ideally suited for the in vivo release of macromolecules. As a way to further retard the rapid release of the proteins. [Pg.209]

Another approach to characterization of PO was explored by Mahdavi and Nook (2008) and by Zhang (2009). In both cases, TREE and FT-IR were used for analyzing a series of different polymers or copolymers, e.g., LDPE, HDPE, LLDPE and C2+8 copolymers, PE, eicosane (C20), ethylene-vinyl acetate copolymer (EVAc), PS, PS-g-EVAc, ethylene-methyl acrylate (EMA), respectively. In both articles a p-TREF was used, FT-IR furnishing the information on polymer concentration and composition. However, while Mahdavi and Nook carried out extensive, external testing, Zhang used the CRYSTAF-TREF 200-1- connecting the FT-IR spectrometer to MW detectors. Both teams stressed the benefits of the FT-IR detectors. [Pg.1577]
