(chemistry) Any of two or more compounds with the same molecular formula but with different structure.
(organic chemistry) A long or larger molecule consisting of a chain or network of many repeating units, formed by chemically bonding together many identical or similar small molecules called monomers. A polymer is formed by polymerization, the joining of many monomer molecules.
(physics) Any of two or more atomic nuclei with the same mass number and atomic number but with different radioactive properties.
A material consisting of such polymer molecules.
A compound which is isomeric with another body or compound; a compound having the same chemical composition as another compound; a member of an isomeric series.
Any one of two or more substances related to each other by polymerism; specifically, a substance produced from another substance by chemical polymerization.
a compound that exists in forms having different arrangements of atoms but the same molecular weight
a naturally occurring or synthetic compound consisting of large molecules made up of a linked series of repeated simple monomers
In chemistry, isomers are molecules or polyatomic ions with identical molecular formulas — that is, same number of atoms of each element — but distinct arrangements of atoms in space. Isomerism is existence or possibility of isomers.
A polymer (; Greek poly-, + -mer, ) is a substance or material consisting of very large molecules, or macromolecules, composed of many repeating subunits. Due to their broad spectrum of properties, both synthetic and natural polymers play essential and ubiquitous roles in everyday life.
