Hydrolysis Behavior of Regenerated Celluloses With Different Degree of Polymerization Under Microwave Radiation

open access: yesBioresource Technology, 2015
This work studied the hydrolysis behavior of regenerated celluloses (RCs) with different degree of polymerization (DP) by using the catalyst of dilute acid under microwave radiation.

Evaluation of dimensional accuracy and degree of polymerization of stereolithography photopolymer resin under different postpolymerization conditions: An in vitro study.

The Journal of prosthetic dentistry (Print), 2020
STATEMENT OF PROBLEM The appropriate postpolymerization of stereolithography (SLA) resins with the least effect on dimensional accuracy and with optimal polymerization is unclear.

Taste Detection of Maltooligosaccharides with Varying Degrees of Polymerization

Journal of Agricultural and Food Chemistry, 2023
Previous 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, 1975
AbstractSelf‐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.

Relationships between degree of polymerization and activities: A study on condensed tannins from the bark of Ficus altissima.

International Journal of Biological Macromolecules
Condensed tannins were isolated from the bark of Ficus altissima and fractionated into four subcomponents on a Sephadex LH-20 column with 60 %, 80 %, 100 % methanol, and 70 % acetone, separately.

Degree of polymerization of a vesicle membrane

the 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, 1953
THE 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 ...

Palladium ion-imprinted polymers with PHEMA polymer brushes: Role of grafting polymerization degree in anti-interference

Chemical Engineering Journal, 2019
Ion-imprinted polymers (IIPs) exhibit great potential as the adsorbent for adsorption of palladium from the industrial wastewater. However, co-existence of complicated water matrixes can readily block the imprinting cavities and disturb the adsorption of

Determination of the cumulative degree of polymerization for the dead‐end polymerization of styrene

Journal of Polymer Science Part A: Polymer Chemistry, 2002
AbstractThis 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 ...
