Polycarbonate and Polymethyl Methacrylate

This was done by Rothwell et al. [58] and Brown et al. [59-61]. The materials under investigation were mainly polystyrene, polycarbonate, and polymethyl methacrylate. Step-wise or oscillatory deformations were performed and the influence of thermal treatment or chemical additives, such as solvents and plasticizers was studied. [Pg.146]

To examine thermal-physical characteristics the lamellar material on polycarbonate and polymethyl methacrylate basis about 10 mm high was prepared. Three layers of polymethyl methacrylate and two layers of poly-... [Pg.238]

Some polymers are essentially amorphous (e.g., polystyrene, acrylonitrile butadiene styrene copolymer, polycarbonate, and polymethyl methacrylate) while others are semicrystalline (e.g., polyolefins and polyamides). The former tend to have a wide melting temperature range with a comparatively high melt strength, while semicrystalline polymers tend to have a narrow melting temperature range and frequently a low melt strength. [Pg.172]

Wohitjen and Dessy [106, 107] described a surface acoustic wave (SAW) device for conducting a thermomechanical analysis measurement of the on polyethylene terephthalate, polytetrafluoroethylene bisphenol A, polysulfone, polycarbonate, and polymethyl methacrylate. There are several factors that distinguish the SAW device as a useful monitor of polymer T. The device is very sensitive, thereby permitting very small samples to be used. Preparation and mounting of the sample are simple and rapid. The device is quite rugged and possesses a small thermal mass, which permits fairly rapid temperature changes to be made. [Pg.116]

Nonlinear oscillatory viscoelastic behavior of glassy polycarbonate and polymethyl methacrylate has been investigated in a thorough study by Davis and Ma-cosko with very nearly homogeneous shear strains up to 4%. The analog of equation 8, derived in the same manner from the extension of the Boltzmann su-... [Pg.452]
