Papillomavirus microbicidal activities of high-molecular-weight cellulose sulfate, dextran sulfate, and polystyrene sulfonate.

The high-molecular-weight sulfated or sulfonated polysaccharides or polymers cellulose sulfate, dextran sulfate, and polystyrene sulfonate were tested for microbicidal activity against bovine papillomavirus type 1 (BPV-1) and human papillomavirus type 11 (HPV-11) and type 40 (HPV-40). In vitro assays included the BPV-1-induced focus-forming assay and transient infection of human A431 cells with...

Absolute Molecular Orientational Distribution of the Polystyrene Surface

Vibrationally resonant sum frequency generation (VR-SFG) has been used to study the absolute molecular orientational distribution of the pendant phenyl groups at the free surface of polystyrene (PS) thin films on oxidized Si substrates. Characterization of the dependence of the VR-SFG on film thickness allows unique identification of the origin of the signal, e.g., free surface, bulk, or buried...

Potential Use of Graft Copolymers of Mercerized Flax as Filler in Polystyrene Composite Materials

Graft copolymerization of binary vinyl monomers onto mercerized flax fiber was carried out for the enhancement of mechanical properties of polystyrene composites. Binary vinyl monomer mixture of AA+AN has been found to show maximum grafting (33.55%) onto mercerized flax. Graft copolymers thus synthesized were characterized with FT-IR spectroscopy, SEM, and TGA techniques. Mercerized flax (MF) s...

Previously we demonstrated ultra-dense patterning using 2 kg/mol polystyrene negative electron beam resist that has low sensitivity [16]. To drastically improve its sensitivity, here we studied the expos...

Synthesis of polyethene–graft–polystyrene copolymers from linear polyethene-containing cyclopropane rings

An efficient procedure to produce polyethene–graft–polystyrene (E-C3–graft–PS) copolymers by simple thermal treatment at 200 1C of polyethene (PE)-containing cyclopropane ring units (E-C3) in the presence of a high excess of styrene is reported. The high treatment temperature likely induces the breaking of the constrained cyclopropane rings, leading to the formation of radicals on the PE chains...
