Controlling the Degree of Branching in Vinyl Polymerization
Progress in Polymer Science, 2000Abstract Branching is an important tool for a synthetic polymer chemist in order to control the macroscopic properties of polymers. In condensation polymers, branching can be controlled by copolymerization of an AB2 type monomer with an AB type monomer.

Taste Detection of Maltooligosaccharides with Varying Degrees of Polymerization
Journal of Agricultural and Food Chemistry, 2023Previous studies have shown that humans can taste maltooligosaccharides [MOS; degree of polymerization (DP) of 3-20] but not maltopolysaccharides (MPS; DP of >20) and that their taste detection is independent of the canonical sweet taste receptor. The objectives of this study were to determine the DP ranges of target stimuli that are tasted and further

Degree of polymerization of acrylic bone cement
Journal of Biomedical Materials Research, 1975AbstractSelf‐curing poweder‐liquid admixed acrylic systems are used for internal fixation of total hip and total knee prostheses. Gel permeation chromatography revealed that the polymer chain length distributions of set cements were basically unaffected by their curing pressures.

Degree of polymerization of a vesicle membrane
Macromolecules, 1984the chains. This is not the reason for the low anisotropy of poly(4BCMU) single crystal, since we adopted evaporated-gold electrodes cov- ering the edges of the specimen completely. Then, the difference in the anisotropy between poly(4BCMU) and PDA-TS single crystals might have resulted from the difference in their crystal forms.

Degree of Polymerization of Deoxyribonucleic Acid
Nature, 1953THE improvement of methods for isolating cell nuclei requires the establishment of suitable criteria of nuclear intactness which may be used to evaluate changes in technique1. The following experiments were performed in the course of an effort to devise methods for following changes in the degree of polymerization of deoxyribonucleic acid during ...

Determination of the cumulative degree of polymerization for the dead‐end polymerization of styrene
Journal of Polymer Science Part A: Polymer Chemistry, 2002AbstractThis article explores the use of a new relation correcting theoretical (DPn) with experimental values obtained in the dead‐end polymerization of styrene with azocompound. The syntheses were realized for several starting initiator‐to‐monomer ratios (C0's); values comprised between 10 and 0.1%, and the experimental (DPn) were obtained by size ...

Degree of Branching in Polymeric Chains
Russian Chemical Reviews, 1969The degree of branching of polymeric chains is one of the most important molecular parameters which determine the physicomechanical and technological properties of the polymers. The results of theoretical calculations of the influence of the degree of branching on the dimensions and nydrodynamic properties of the macromolecules are surveyed.

Anion Template Effect and the Polymerization Degree – Diversity through Flexibility
European Journal of Inorganic Chemistry, 2005AbstractTwo 2D (M1 and M2) and one 1D (M3) metal‐organic frameworks (MOFs) have been prepared from pyridine functionalized tetradentate ligand tetrakis(nicotinoxymethyl)methane TNM with silver tetrafluoroborate, nickel chloride, and copper hexafluorophosphate.

Quantitative Fractionation of Grape Proanthocyanidins According to Their Degree of Polymerization
Journal of Agricultural and Food Chemistry, 1999A method was developed for the fractionation of grape (seed or skin) proanthocyanidins according to their degree of polymerization. After precipitation in chloroform/methanol (75:25, v/v), the grape proanthocyanidins were deposited onto an inert glass powder column and sequentially dissolved in several fractions by increasing proportions of methanol in
