Description

Ionomers are a type of polymer with unique physical properties due to specific chemical/ionic interactions in discrete regions of the material. Examples of ionomers include polystyrenes (used in the production of toys), and polyacrylics (used in lenses.) This is the first book in 20 years that surveys the field of ionomers for the nonspecialist. The book relates the molecular structure of ionomers with their physical properties and interactions, including such concepts as the glass transition, mechanical properties of random-styrene based and other ionomers. It offers a brief discussion of materials with special architecture, such as blocks and telechelics and concludes with a discussion of ionomer blends, applications, and unsolved problems.

Advantages

Good low temperature toughness. Very good barrier properties (better than Polyethylene’s). Transparent. Good oil and solvent resistance little tendency to solvent stress cracking. Better puncture resistance than LDPE film.

Disadvantages

Poor resistance to acids. Similar (poor)weathering characteristics as Polyethylene. Poor creep resistance.

Applications

Puncture resistant film for pouches and blister packs. Bottles and containers, tool handles. Covers for golf balls and skittles. Protective pads for shoes and boots.
