New Monomers and Polymers book. by Charles U. Pittman. New Monomers and Polymers (Polymer Science and Technology Series). 0306414775 (ISBN13: 9780306414770). Interest in preparing new polymers peaked about 1966.

Polymers are large molecules made up of many smaller subunits. Fatty acids are the monomers for lipids, for example, and regardless of how they are bonded (as a saturated or unsaturated fat, for example), they will form lipids. Nucleotides form nucleic acids (eg. The wide array of configurations and bonding patterns result in vast molecular diversity. Carbohydrates, lipids, proteins, and nucleic acids are all examples of polymers which is why polymers are a key component of human composition.

Shrinkage was determined from the density differences between monomers and polymers, and polymer water sorption was determined gravimetrically. Wetting ability was measured by contact angle against human dentin and enamel as well as poly(methyl methacrylate) and glass.

Polymers, such as Polythene and Polyamide are built from subunits called . Dr. Helmenstine holds a P. Monomers-repeating molecular units-are connected into polymers by covalent bonds.

Polymers, such as Polythene and Polyamide are built from subunits called Monomers. in biomedical sciences and is a science writer, educator, and consultant. She has taught science courses at the high school, college, and graduate levels. The word monomer comes from mono- (one) and -mer (part). Monomers are small molecules which may be joined together in a repeating fashion to form more complex molecules called polymers.

Needs and opportunities, mentioned in the Panel's list, included polymerization methods, specialty polymers, high performance materials, and in situ (reaction injection molding) polymerization for direct conversion of monomers/oligomers to useful shapes.

Polymer science or macromolecular science is a subfield of materials science concerned with polymers, primarily synthetic polymers such as plastics and elastomers. This science comprises three main sub-disciplines: Polymer chemistry or macromolecular chemistry is concerned with the chemical synthesis and chemical properties of polymers.

Interest in preparing new polymers peaked about 1966. Since that time, industrial and government support for the synthesis and study of new polymers has steadily declined. Gone are the good days when government funds supported a great push to attain ulti­ mate thermal stability for organic polymeric materials. Gone are the good days when many chemical companies, encouraged by the obvious potential for rewards, had great interest and provided support for preparing new polymers. We now often hear managers say "we have enough polymers" or "all we need to do is find additional and better ways to use existing polymers. " The latter often in­ cludes the statement, "we can get the new materials that are wanted from polymer alloys or blends. " Interest in preparing new monomers has also waned, even though it is well recognized that monomers with special functionality are greatly needed to fine-tune existing polymers for specific tasks. Shrinkage of interest in new monomer and polymer research has not come about solely as a result of the obvious maturity of the polymers industry. Since uses for polymers continue to grow and there is still room for good concepts to study, lack of market growth and fields of study have probably not significantly contribu­ ted to that shrinkage.
