High Solid Acrylic–Melamine Latexes with Tunable Crosslinking Capability
(Wiley VCH Verlag, 2019-04)
Miniemulsion polymerization is employed to produce high solid content (50%) acrylic/melamine latexes with varied crosslinking capability, for their potential application as waterborne crosslinkable coatings. This synthesis ...
A lateral flow immunoassay based on colored latex particles for detection of canine visceral leishmaniasis
(Elsevier Science, 2020-07)
Canine visceral leishmaniasis (CVL) is the major source of human visceral leishmaniasis. To control the spread of this disease, early and accurate detection of infected dogs is critical but challenging. The serological ...
On the Viscosity of Concentrated Suspensions of Charged Colloids
(Planta Piloto de Ingeniería Química, 2005-12)
This work is concerned with the theoretical estimation of the low-shear viscosity of concentrated suspensions of charged-stabilized latex particles. Calculations are based on the assumption that particles interacting through ...
Effect of natural rubber on wood-reinforced tannin composites
(John Wiley & Sons Ltd, 2007-08)
Natural rubber latex was added to composite materials formulated from a quebracho tannin adhesive crosslinked with hexamethylenetetramine and wood flour as a reinforcing filler. The final microstructure of the thermoset ...
Multiple response optimization of styrene–butadiene rubber emulsion polymerization
(Pergamon-Elsevier Science Ltd, 2009-04)
A multiple response optimization of styrene-butadiene rubber (SBR) emulsion batch polymerization is proposed. Several properties of latex and rubber were optimized to obtain a particular grade of SBR, namely 1712. Artificial ...
Batch Emulsion Polymerization of Vinyl Chloride: Effect of Operating Variables on Reactor Performance
(Planta Piloto de Ingeniería Química, 2001-12)
We analyze experimentally the effect of several operating conditions on conversion and molecular weight distributions of PVC obtained in batch emulsion polymerization. The operating variables studied were reaction temperature, ...
Collective diffusion in charge-stabilized suspensions: Concentration and salt effects
(American Institute of Physics, 2007-12)
The authors present a joint experimental-theoretical study of collective diffusion properties in aqueous suspensions of charge-stabilized fluorinated latex spheres. Small-angle x-ray scattering and x-ray photon correlation ...
New hybrid acrylic/collagen nanocomposites and their potential use as bio-adhesives
Nowadays material science is trying to design products that combine the adaptability of synthetic polymers with the structure and functionality of biopolymers. In this context, the present work investigates the production ...
Mineral-Deficiency Symptoms Displayed by Papaya Plants Grown under Controlled ConditionsTítulo en español.
(University of Puerto Rico Mayagüez Campus Agricultural Experiment Station, 1978)
Long-lasting isothiazolinone-based biocide obtained by encapsulation in micron-sized mesoporous matrices
The use of mesoporous silica materials as new hosts for stabilizing isothiazolinone-based biocides was investigated. Two types of porous matrices were synthesized: SBA-15 mesoporous silica and mesocellular siliceous foam ...
