The terms polymer and macromolecule do not mean the same thing. A polymer is a substance composed of macromolecules. A polymer is a substance composed of macromolecules. The latter usually have a range of molar masses (unit g mol −1 ), the distributions of which are indicated by dispersity ( Đ ).
A decade later, he moved to the Graduate School of Engineering of Kyoto University, where he was a professor of polymer chemistry. From 2008 to 2010 Sawamoto was president of The Society of Polymer Science, Japan (SPSJ). He is currently a member of the Science Council of Japan. He is one of the editors of Journal of Polymer Science Part A. [1]
1983 – The Award of the Society of Polymer Science, Japan; 2000 – SPSJ Award for Outstanding Achievement in Polymer Science and Technology; 2000 – Nobel Prize in Chemistry; 2000 – Order of Culture and selected as Person of Cultural Merit; 2000 – Professor Emeritus of the University of Tsukuba; 2001 – Special Award of the Chemical ...
Also acid ionization constant or acidity constant. A quantitative measure of the strength of an acid in solution expressed as an equilibrium constant for a chemical dissociation reaction in the context of acid-base reactions. It is often given as its base-10 cologarithm, p K a. acid–base extraction A chemical reaction in which chemical species are separated from other acids and bases. acid ...
Polymers are studied in the fields of polymer science (which includes polymer chemistry and polymer physics), biophysics and materials science and engineering. Historically, products arising from the linkage of repeating units by covalent chemical bonds have been the primary focus of polymer science.
Polymer chemistry is a sub-discipline of chemistry that focuses on the structures, chemical synthesis, and chemical and physical properties of polymers and macromolecules. The principles and methods used within polymer chemistry are also applicable through a wide range of other chemistry sub-disciplines like organic chemistry , analytical ...
In polymer chemistry, polymerization (American English), or polymerisation (British English), is a process of reacting monomer molecules together in a chemical reaction to form polymer chains or three-dimensional networks. [1] [2] [3] There are many forms of polymerization [4] and different systems exist to categorize them.
A repeat unit is sometimes called a mer (or mer unit) in polymer chemistry. "Mer" originates from the Greek word meros, which means "a part". The word polymer derives its meaning from this, which means "many mers". A repeat unit (mer) is not to be confused with the term monomer, which refers to the small molecule from which a polymer is ...
