Sentence examples for pu formation from inspiring English sources

While the amount of PU formation remained almost the same, the copolymerization of VER was greatly affected by temperature, by the composition of SINs and by the molecular crosslinking nature of both components.

Furthermore, the thermal behaviour during the synthesis of SINs from VER containing hydroxyl groups was examined and showed that, when the secondary hydroxyl groups in VER were included for the metering of isocyanate in the feed for PU formation, inter-component chemical binding between the two networks should occur, resulting in a completely different molecular architecture of SINs.

The mechanical properties of PU, PU-Gel, and PU-SF scaffolds were separately tested.

Data were compared between cells grown on PU, PU-Gel, and PU-SF scaffolds and TCPS.

Quenched systems corresponding to different reaction extents of polyurethane (PU) network formation have been studied using broadband dielectric spectroscopy in order to apprehend the evolution of α-relaxation during gel formation.

As illustrated in Fig. 1, TAM posits that both PEOU and PU influence the formation of favourable Att associated with the use of technology, which, in conjunction with PU, generate individuals' greater BI to use the technology.

Our results also indicate there is a significant increase in tensile strength and modulus at fairly low CNC volume fractions (e.g., 2.0 and 4.1 vol%) because of the appreciable interactions between DDSA-CNC and PU through the formation of hydrogen bonding.

Descriptions of approaches to improve the thermal stability in PUs such as formation of poly urethane-isocyanurate), poly urethane-isocyanurate and poly urethane-oxazolidoneddition to other methods such as poly urethane-oxazolidoneng or increandd aromatic ring concentration, azomethane linkages as well as use of hypoly urethane-imide as crosslinking agents is given.

ATR-FT-IR spectra of the PUs showed that the formation ratio of hydrogen bond between the PU chains around PRXs increased with increase in the filling ratio.

Among them, approaches based on energy detection constitute the most preferable sensing techniques, regarding practical implementation, since they do not take for granted any knowledge on the specific characteristics of underlying PU signals and/or the formation of secondary channels.

Tensile strength and mechanical stability of modified HTPB-PU was found to be better than the native HTPB-PU owing to the formation of HSD.
