Ionomer



 
 
An ionomer is a polymer
Polymer

A polymer is a large molecule composed of repeating structural units typically connected by covalent chemical bonds. While polymer in popular usage suggests plastic, the term actually refers to a large class of natural and synthetic materials with a variety of properties....
 that comprises repeat units of both electrically
Electric charge

Electric charge is a fundamental conserved property of some subatomic particles, which determines their electromagnetic interaction. Electrically charged matter is influenced by, and produces, electromagnetic fields....
 neutral repeating units and a fraction of ion
Ion

An ion is an atom or molecule which has lost or gained one or more electrons, giving it a positive or negative electrical charge. According to the Bohr_model this will be from or in the outer shield 'n'....
ized units (usually no more than 15 percent). Ionomers have unique physical properties including electrical conductivity and isoviscosity -- increase in ionomer solution viscosity with increasing temperatures.(see conducting polymer ).

Some commercial applications for ionomers are golf ball
Golf ball

A golf ball is a ball designed to be used in the game of golf.Under the Rules of Golf, a golf ball weighs no more than 1.620 ounces , has a diameter not less than 1.680 in , and performs within specified velocity, distance, and symmetry limits....

Semipermeable membrane

A semipermeable membrane, also termed a selectively-permeable membrane, a partially-permeable membrane or a differentially-permeable membrane, is a membrane that will allow certain molecules or ions to pass through it by diffusion and occasionally specialized "facilitated diffusion." The rate of passage depends on the press...
