For example, it is now possible to prepare high molecular weight polymers (molecular weight > 50,000), to control the stereo-structure (tacticity) of the C–C main chain, and to quantitatively ...

The monomer structure itself may significantly contribute to the formation of a regulated polymer chain structure through intermolecular repulsion or attraction. An advantage of these polymer ...

Intra-polymer structure characteristics: Polymer chains are mostly ‘soft’, ‘stiff’ or in-between. The intra-polymer structure characteristics of the polymers decide whether a long chain polymer is ...

Researchers describe a new polymer structure called a bilayer-folded mesophase that has been discovered through a random copolymer sequence. Polymers, large molecules made up of repeating smaller ...

The process causes the molecules to bond in a linear, branched or network structure, resulting in polymers. These chains of monomers are also called macromolecules. Most polymer chains have a ...

Plumber's nightmare structure in block polymers Date: January 22, 2024 Source: Pohang University of Science & Technology (POSTECH) Summary: Scientists solve a long-standing block copolymer ...

In biodegradable systems, the erosion of the polymer molecular structure occurs when the chain fragments in crystalline systems dissolve without any chemical interaction. However, the dissolution ...

The large storage capacity is predicted because numerous hydrogen molecules are attracted to the metal atoms that lie along the polymer chain. Using a series of first-principles electronic-structure ...

As polymers are formed through a process called polymerization, the monomers are connected through a chain. As the chain develops, the structure of the polymer determines its unique physical and ...
