Ambient Polymerization of Acrylic Pressure Sensitive Adhesives
Traditional solution acrylic polymers for pressure sensitive adhesives (PSA) are synthesized using conventional free radical initiation systems based upon organic peroxide or azo compounds 1 . Such syntheses are heat activated and employ solvent reflux temperatures during the polymerization process. The resulting acrylic polymers are formed with a relatively broad molecular weight distribution ...
متن کاملPressure-induced polymerization of acrylic acid: a Raman spectroscopic study.
We report here the first in-situ Raman spectroscopic study of pressure-induced structural and polymeric transformations of acrylic acid. Two crystalline phases (I and II) were observed upon compression to approximately 0.3 and approximately 2.7 GPa. Phase I can be characterized with a single s-cis molecular conformation with possibly a similar structure to the low-temperature phase, while phase...
متن کاملfunctionality effect of acrylic pressure sensitive adhesive formulations on release performance and adhesion properties of stimulants in an adhesive patch
drug-in-adhesive transdermal drug delivery systems )tddss) containing stimulants, termed as energetic substances, such as caffeine and pantothenic acid, were studied. caffeine is a white crystalline substance and a stimulant to central nervous system. in humans, caffeine acts as a central nervous system stimulant, temporarily warding off drowsiness and restoring alertness. pantothenic acid, al...
متن کاملProperties of Water-based Acrylic Pressure Sensitive Adhesive Films in Aqueous Environments
Water-base pressure sensitive adhesives dominate the market of adhesives applied to paper. These materials are formulated as emulsions of acrylic polymers in water. Surfactants are used to stabilize the hydrophobic polymer particles. When water-based adhesives are dried, particles coalesce and surfactant segregates to interparticle domains that provide pathways for water to enter the adhesive f...
