Development and sensory analysis of shampoo for curly hair
(2013-07-15)
Objective: This study aimed to compare the sensory performance of a shampoo formulation with Polyurethane-14, AMP-acrylates copolymer (PAAC) in relation to control formulation in curly and natural hair tresses. Methods: ...

Ionomer synthesis by emulsion polymerization of styrene and sodium acrylate
(1997)
The emulsion copolymerization of styrene and sodium acrylate is reported using either a water-soluble initiator (potassium persulfate, or KPS), or an oil-soluble one [2,2-azoisobutyronitrile (AIBN)]. Reaction rates are ...
Mechanical performance of styrene-2-ethylhexyl acrylate polymers synthesized by semicontinuous emulsion polymerization varying feed composition
(2006)
A semicontinuous emulsion process varying comonomer feed composition in the course of the reaction is used here to produce copolymer chains of different composition as conversion proceeds. Polymeric material global composition ...
Investigation and analysis of urban noise for sustainability
(1997)
The emulsion copolymerization of styrene and sodium acrylate is reported using either a water-soluble initiator (potassium persulfate, or KPS), or an oil-soluble one [2,2-azoisobutyronitrile (AIBN)]. Reaction rates are ...
Poly[ethylene-co-(acrylic acid)]-based nanocomposites: Thermal and mechanical properties and their structural characteristics studied by Raman spectroscopy
(2013)
Two poly(styrene oxide)-poly(ethylene oxide) (PSO-PEO) triblock copolymers with different chain lengths were analyzed as potential chemotherapeutic nanocarriers, and their ability to inhibit the P-glycoprotein (P-gp) efflux ...
Evaluación del comportamiento fisicoquímico y antimicrobiano de complejos con polielectrolitos
(Universidad Nacional de ColombiaBogotá - Ciencias - Doctorado en Ciencias FarmacéuticasDepartamento de FarmaciaFacultad de CienciasBogotá, ColombiaUniversidad Nacional de Colombia - Sede Bogotá, 2021)
Las interacciones electrostáticas entre un polielectrolito y una molécula ionizable conducen a la formación de un complejo polielectrolítico (CPE), cuyas propiedades fisicoquímicas se diferencian de los materiales de ...
