New piezoelectric polymers have been under study, some of these showing ferroelectric hysteresis. Among applications, ultrasonic transducers in the form of hydrophones, sonar arrays, and focussed medical sensors are attracting wide current attention, while imaginative new uses for these polymers are ...
a wide range of applications is possible for this polymer. The chemical resistance. temperature stability. and transparency provide uses in medical equipment such as hypodermic syringes. blood collection and transfusion equipment. pacemaker parts. and respiration equipment; in chemical laboratory equipment ...

T his chapter compiles the information available in the field of polymers and plastics regarding structure and properties, and indicates significant unique uses. Special developments within each family of polymers will be highlighted. About 40 families of polymers will be briefly described, appearing ...
Polyethylene terephthalate, or PET, a strong, stiff synthetic fiber and resin and a member of the polyester family of polymers. PET is spun into fibers for permanent-press fabrics, blow-molded into disposable beverage bottles, and extruded into photograp
Aromatic polyimides are derived from an aromatic dianhydride and diamine. Semi-aromatic ones contain any one of the monomer aromatics: i.e., either the dianhydride or diamine is aromatic, and the other part is aliphatic. Aliphatic polyimides consist of the polymers formed as a result of the ...

Oriented products made from synthetic polymers have found many uses since they became widely available about 40 years ago. Their commonest form is as fibres; polymeric fibres find applications in products from clothing to aircraft manufacture. The fibres can have a remarkably wide range of physical...
major industrial polymers: Polyethylene (PE) The basic polyethylenecompositioncan be modified by the inclusion of other elements or chemical groups, as in the case of chlorinated and chlorosulfonated polyethylene. In addition, ethylene can be copolymerized with other monomers such asvinyl acetateorpropy...
