Mechanical and Thermal Properties of PLLA/PCL Modified Clay Nanocomposites

“…DTG thermograms of PEMA/CAB/OMMT nanoblends (Figure ) show only one peak corresponding to T max witch shifts towards higher temperatures compared to that of the (PEMA/CAB) blend and CAB polymer . The T max of (30/70/1%) nano‐blend shifted to a higher temperature values (Table ).…”

Poly (ethyl methacrylate)/Cellulose acetate butyrate/organically modified Algerian Bentonite nano‐blends (PEMA/CAB/OMMT) are prepared via solution intercalation method. Transmission electron microscopy (TEM) investigations reveal that depending on the OMMT loading, intercalated and exfoliated silicate layers nano‐blends were obtained. These nano‐blends exhibit an overall improved thermal stability compared to the pure (PEMA/CAB) blend as evidenced by thermogravimetric analysis (TGA).

“…These were due to the decomposition of crosslinked urethane-methacrylate terminal groups. 31 Table 3 presents the results of the solubility tests of the hyperbranched oligomers at room temperature. All of the hyperbranched oligomers are easily dissolved in strong polar organic solvents, such as DMF, DMAc and DMSO.…”

A new type of hyperbranched polyurethane terminated by carboxyl groups (HBP-COOH) has been synthesized by thiol-ene "click" reaction. The carboxyl groups of HBP-COOH were further modified by glycidyl methacrylate at different feed ratio to produce a series of hyperbranched polyurethane acrylate oligomers containing carboxyl groups (HBPUA-COOHs). The structures of products were characterized by FT-IR, 1 H-NMR spectroscopy and gel permeation chromatography (GPC). The photosensitive groups of these synthesized HBPUA-COOHs were measured with UV-Vis spectrophotometer. It was shown that the HBPUA-COOHs had sharp absorption bands at about 205 nm. The photosensitivities were characterized by FT-IR with different curing time. The thermal properties of samples were characterized by DSC and TGA. In addition, the solubilities and viscosity of the HBPUA-COOHs were also examined. These synthesized hyperbranched polyurethane acrylate oligomers containing carboxyl groups, which have well-defined structures with very narrow polydispersities, can be used in many fields such as coatings, adhesives and photoresists, ect.
