The largest polymer tested was severalfold more potent than AIG at similar concentrations.
Because of its high accuracy, high sensitivity, low cost and convenience, the proposed method could be widely used in polymer testing, especially in density-based testing.
The polymer tested was a graft copolymer of polylactic acid (PLA) synthesized with the rationale to improve the toughness of the related PLA homopolymer.
According to the definition in the Handbook of Polymer Testing [19], "Young's modulus" is the modulus of elasticity in tension and defined as ratio of stress difference to the corresponding strain difference (stress/strain).
It is shown that the hole depth has a stabilizing influence, i.e. the onset of instabilities occurs at higher shear rates, in the long chain branched polymer tested, whereas for the linear polymer tested it has a destabilizing effect on the stick-slip instability i.e. the onset of stick-slip occurs at lower shear rates.
The polymer testing showed that synthesized molecularly imprinted polymers have high affinity and selectivity for corresponding templates in aqueous environment, with imprinting factors of 2.6 for cocaine and 1.4 for methadone and deoxyephedrine.
A molecular weight cut-off, beyond which drug release was greatly hindered by the hydrogel mesh size, was established for each polymer tested.
This study is a continuation of the previous research on experimental design optimisation of PVA-collagen hydrolysate blends (P. Alexy, D. Bakoš, S. Hanzelová, L. Kukolíková, J. Kupec, K. Charvátová, E. Chiellini, P. Cinelli, Polymer Testing 2003, 22 doi 10.1016/S0142-9418 03 00016-3).
Residues from the surfaces of model polysiloxane coatings containing oil repeatedly promoted transglutaminase activity in all but one polymer tested.
The viscosity and specific gravity of foam contrast were measured using viscometer (HBDV-II + Pro, Brookfield Engineering Laboratories, Inc., MA, USA) and electronic densitometer (MD-300S, Alfa Mirage Co., Ltd., Osaka, Japan) at ambient temperature of 23°C by the external testing laboratory (Korea Polymer Testing & Research Institute, Seoul, Korea).
Specifically, several unique metal-on-polymer test objects, whose interfaces were point, non-point, and circular contact areas, were ultrasonically imaged.
