《Assembly of Short-Chain Amphiphilic Homopolymers into Well-Defined Particles》 was published in Langmuir in 2020. These research results belong to Swan, Stephanie; Egemole, Franklin O.; Nguyen, SonBinh T.; Kim, Jun-Hyun. Category: chlorides-buliding-blocks The article mentions the following:
Linear homopolymers of norbornene (NBE) derivatives equipped with short-chain alc. pendant groups were prepared by ring-opening metathesis polymerization (ROMP) and subsequently assembled into well-defined structures in alc. solvents. The ratios of hydrophobic carbons and hydrophilic alc. groups at the repeating monomeric unit in these short-chain amphiphilic polymers were found to play an important role in determining the size and distribution of the final globular structures. Unlike the assembly of other linear homo- and copolymers possessing long-chain amphiphilicity, NBE-based linear polymers were readily transformed into spherical particles with a layered conformation, whose sizes range from a few hundred nanometers to micrometers with narrow distributions, simply by controlling the concentration and mol. weights of the linear homopolymers without using any surfactants. In addition, the degree of the intermol. forces with solvents (e.g., solvation) possessing different surface tensions and polarities highly affected the final diameter and distribution of the polymer particles, implying the importance of the selection of a proper solvent to regulate their structural features. As such, understanding the assembly of these types of short-chain homopolymers into uniform particles can allow for regulating the transformation of diverse linear amphiphilic polymers into precisely controlled structures for various applications. In the experiment, the researchers used many compounds, for example, Benzylidenebis(tricyclohexylphosphine)dichlororuthenium(cas: 172222-30-9Category: chlorides-buliding-blocks)
Benzylidenebis(tricyclohexylphosphine)dichlororuthenium(cas: 172222-30-9) is a ruthenium-based olefin metathesis catalyst. It is useful for olefin cross metathesis (CM) and ring closing metathesis (RCM) of terminal olefins under a variety of reactions conditions, and so on.Category: chlorides-buliding-blocks
