Stereoregular Polymers and Stereospecific Polymerizations: ...
STEREOREGULAR POLYMERS HAVING A HIGH STERIC PURITY In the
polymers, in which monomeric units can show stereoisomerism phenomena,

Stereoregular Polyvinyl Nitrate
Isotactic polyvinyl nitrate (PVN) was prepared to investigate the effect of stereorgularity on the physical properties of PVN. The isotatic PVN had a higher softening point and was more difficult to stabilize than regular PVN. (Author).

Polymer Science and Technology
To illustrate this, let us consider two examples of stereoregular polymers. Table
3.8 shows the properties of two isomers: cis- and r/wu-polyisoprene. It is obvious
from the table that the stereoregular trans form is more readily packed and ...

... from differences in the chain segmental motion between stereoregular
polymers or sequences but also from differences in preferred conformations
between the stereoregular polymers or sequences which lead to different
average distances ...

Polymer Pioneers: A Popular History of the Science and ...
The breakthrough in developing stereoregular polymers came not from the
physical chemists, but from several teams of chemists in the petrochemical
industry (or on its fringes) who were studying the organometallic chemistry of
olefins.

Current Topics in Polymer Research
Schuerch et al. reported the synthesis of 1,6-α-linked polyglucose, dextran, by the
ring-opening polymerization of 1,6-anhydro-β-D-glucopyranose [3, 4], which was
the first synthetic polysaccharide having a highly stereoregular structure ...

Novel Metathesis Chemistry: Well-Defined Initiator Systems ...
The first attempt to arrange hydrogen bonding in synthetic polymer was made by
Nakahira et al. using stereoregular isotactic poly(methacrylamides).[4,5] The
