In this work, we report the structure and the thermal decomposition behavior of polymer/MMT NPC prepared by random copolymer poly(methyl methacrylate-co-trime-thoxysilylpropyl methacrylate) (PMMA-co-PTMSM) reaction followed by its intercalation into organophilic
MMT (Cloisite 15A[TM]).
After clay incorporation, organophilic
modification was carried out at 80[degrees]C for 1 h under reflux and agitation.
However, the nanocomposites prepared with organophilic
treated clays show a low value of the log normalized average light extinction, which reduces during the reprocessing.
After completion of the clay incorporation, organophilic
modification was carried out at 80 C for 1 h under reflux and agitation.
Montmorillonite is hydrophilic, able to absorb 20-30 times its volume in water, and therefore must be chemically modified to render the surfaces organophilic
PCL/layered silicate nanocomposites were prepared by in situ ring-opening polymerization of [epsilon]-caprolactone using conventional initiator to induce polymerization in the presence of an organophilic
clay, such as organometallic initiators [16, 17].
High-purity talc fillers include organophilic
and hydrophobic products in various particle-size distributions.
These systems include GF-filled PA6/LCP (5), (6), GB-filled PA6/ LCP (4), GB-filled PC/LCP (19-21), Nano Si[O.sub.2]-filled PC/ LCP (14), Nano Si[O.sub.2]-filled PSF/LCP (22), nano-clay (organophilic
montmorillonite, OMMT)-filled PA6/LCP (23), and whisker-filled PSF/LCP (24), (25).
Offers a high-purity, asbestos-free platy talc, which is organophilic
These materials are also available with organophilic
surface modification to improve dispersion and reduce energy requirements during processing.
To make them miscible with polymers, they require modification usually by cation exchange with quaternary ammonium salts, which enlarge both the silicate intergallery space and exchange hydrophilic groups with organophilic
Cellular findings include protrusions through the cell membrane ("blebbing"), the presence of organophilic
squamoid cells when stained according to Papanocolaou, and a fine vacuolization in the perinuclear area when a May-Grunwald-Giemsa stain is used.
