“…Bisoxazolines are quite interesting as coupling agents because they present good thermal stability and high reactivity toward carboxy,23 phenol,24 and thiophenol end groups 25. They have also been used as reactive compatibilizers in polymer blends 26, 27. Culbertson16 fully described the use of these cyclic iminoethers in step‐growth reactions and polymerizations in a recent publication.…”

Polyamide-polyester multiblock copolymers were synthesized through the reaction of ␣,-dicarboxy polyamides and polyesters with various arylene bis(2-oxazoline)s. 2,2Ј-(2,6-Pyridylene)bis(2-oxazoline) was very reactive and yielded multiblock copolymers with number-average molar masses ranging from 15,000 to 25,000 after 30 min of reaction in the bulk at 200°C. The molar masses and thermal properties of the resulting random multiblock copolymers (glass-transition temperature, melting temperature, and melting enthalpy) were close to those of their alternating homologues prepared by conventional polycondensation between diamino polyamides and dicarboxy polyesters. This showed that the presence of coupling agent moieties in the polymer chains did not exert a significant influence on the block copolymer morphology. The chain-coupling method showed several advantages over conventional polycondensation: a much shorter reaction time, a lower temperature, no byproducts, and easy control of the final copolymer properties through the mass ratio of the starting oligomers.

Level 3 automated driving requires a driver to operate a vehicle in response to a takeover request according to the Society of Automotive Engineers; therefore, the driver should maintain a state of wakefulness. The study aimed to evaluate and verify whether the presented stimuli, i.e., saccade-inducing stimuli (SaS) as visual stimuli, scent stimuli (ScS) as olfactory stimuli, and a combination of saccade-inducing and scent stimuli (CoS), can maintain the wakeful state of a driver. A driving simulator (DS) that can reproduce the actual movement of a motor vehicle using a turn table and six-axis motion device is used to simulate driving under four different conditions: no stimulation, SaS, ScS, and CoS. The percentage of eye closure (PERCLOS) and the electroencephalogram (EEG) analysis were used for the quantitative evaluation, while the participants were subjected to subjective evaluation. The results showed that the average increase in arousal time for each condition was 30.2, 53.7, and 82.3% for the SaS, ScS, and CoS cases, respectively. The average reduction rate in the EEG readings was 39.9, 41.0, and 71.4% for the SaS, ScS, and CoS cases, respectively. All participants indicated that the CoS had the highest effect of arousal as a driver stimulation tool.
