Polycarbonates glasses

Where transparency is required, a range of polymers is available. Polystyrene is the least expensive but polymethylmethacrylate has an outstanding high light transmission combined with excellent weathering properties. Also to be considered are the polycarbonates, glass-clear polyamides, SAN, butadiene-styrene block copolymers, MBS polymers, plasticised PVC, ionomers and cellulose esters such as cellulose acetate. 

Indirect evidence of nonequilibrium flucmations due to CRRs in structural glasses has been obtained in Nyquist noise experiments by Ciliberto and co-workers. In these experiments a polycarbonate glass is placed inside the plates of a condenser and quenched at temperatures below the glass transition temperature. Voltage fluctuations are then recorded as a function of time during the relaxation process and the effective temperature is measured ... 

Because the ion-assisted processes enable deposition at temperatures less than 100°C, deposition of diamond like coatings has been attempted on a wide range of substrates, e.g., stainless steel, Copper, ceramics,optical materials (plastics, polymers and polycarbonates),glasses,quartz, sapphire,infrared-transmitting optical materials such as germanium, zinc sulfide and zinc selenide, and a variety of electronic grade materials. Although thin films can be produced... 

Scintillation measurements are usually carried out using 20 ml standard vials, or 6 ml mini-vials equipped with screw caps. Disposable vials are available in polypropylene, polyester or polycarbonate. Glass vials, which must be of low potassium content because the naturally occurring 40K isotope is a /S emitter, can be re-used. Care should be taken that tbey do not get scratched. Cerenkov counting is usually carried out in 1 ml, 500 pi or 250 pi Eppendorf vials, placed either in special adaptors or in 20 ml standard vials. For accurate and reliable measurements, the positioning of the vials must all be the same, to ensure that the counting geometry with respect to the photomultiplier tube is identical.

Filtration is most widely employed, but the variety of filter types and porosities used makes any comparison between the results difficult. Three main types are commonly employed membranes made of cellulose esters or polycarbonate, glass fiber filters and silver filters.

In thermoplastics, the organometallics appear mainly to provide a catalytic support bed for in situ re-polymerization of the polymer matrix, which reflects itself in improved processing. A test on a 40% polycarbonate/glass compound showed improvements in mechanical properties, together with significant improvements in productivity.
