In 2019,Polymers for Advanced Technologies included an article by Kekec, Nur Cicek; Akolpoglu, Mukrime Birgul; Bozuyuk, Ugur; Kizilel, Seda; Nugay, Nihan; Nugay, Turgut; Kennedy, Joseph P.. COA of Formula: C4H11NO. The article was titled 《Calcification resistance of polyisobutylene and polyisobutylene-based materials》. The information in the text is summarized as follows:
Calcification of implanted biomaterials is highly undesirable and limits clin. applicability. Experiments were carried out to assess the calcification resistance of polyisobutylene (PIB), PIB-based polyurethane (PIB-PU), PIB-PU reinforced with (CH3)3N+CH2CH2CH2NH2 I–modified montmorillonite (PIB-PU/nc), PIB-based polyurethane urea (PIB-PUU), PIB-PU containing S atoms (PIBS-PU), PIBS-PU reinforced with (CH3)3N+CH2CH2CH2NH2 I–modified montmorillonite (PIBS-PU/nc), and poly(isobutylene-b-styrene-b-isobutylene) (SIBS), relative to that of a clin. widely implanted polydimethylsiloxane (PDMS)-based PU, Elast-Eon (the “”control””). Samples were incubated in simulated body fluid for 28 days at 37°C, and the extent of surface calcification was analyzed by SEM (SEM), at. force microscopy (AFM), energy-dispersive X-ray spectroscopy (EDX), XPS, and Fourier-transform-IR (FT-IR) spectroscopy. Whereas the PDMS-based PU showed extensive calcification, PIB and PIB-PU containing 72.5% PIB, ie, a polyurethane whose surface is covered with PIB, were free of calcification. PIBS-PU and PIB-PUU, ie, polyurethanes that contain S or urea groups, resp., were slightly calcified. The amine-modified montmorillonite-reinforcing agent reduced the extent of calcification. SIBS was found slightly calcified. Evidently, PIB and materials fully coated with PIB are calcification resistant.4-Aminobutan-1-ol(cas: 13325-10-5COA of Formula: C4H11NO) was used in this study.
4-Aminobutan-1-ol(cas: 13325-10-5) is used in the synthesis of NSAIDs with anti-inflammatory properties. Also used in the synthesis of polyamine transport ligands with specificity against human cancers allowing easy access to specific cancer cells.COA of Formula: C4H11NO
