This adhesive patch includes a backing and an adhesive layer containing rivastigmine and an alkyl(meth)acrylate-based copolymer that does not contain any acrylic monomer component having a carboxy group, the adhesive layer being laid on one side of and integrated with the backing.. .
|Acrylic-modified asphalt rejuvenating emulsion|
A polymer-modified emulsion used for rejuvenating or repairing deteriorated asphalt pavement includes an asphalt phase containing an asphalt and a rejuvenating agent, and an aqueous phase including water, an acrylic polymer or copolymer and an emulsifying agent.. .
|Dry-wet spinning device and method for manufacturing synthetic fiber|
There is provided a dry-wet spinning device for an acrylic precursor fiber bundle for manufacturing carbon fibers, the device enabling stable spinning by making the coagulability of spun yarn (2) uniform by suppressing the vibration of the coagulating liquid surface to make the spun yarn (2) spun downward from a spinneret (1) without the liquid surface being in contact with the spinning surface of the spinneret less susceptible to an accompanying flow reflected by the bottom surface of a spinning bath. To this end, in the present invention, a horizontal flow straightening plate (8) produced from a porous plate or a plate material extending in the direction approximately perpendicular to the direction in which the spun yarn (2) is spun is disposed in a coagulation bath so as to surround the circumference of the yarn spun downward from the spinneret (1).
|Light solidifying device having a magnetic slide cover|
Nail gel curing devices emitting ultraviolet light, as well as methods of their making and use are disclosed. The devices are useful for curing, inter alia, acrylic compositions, more particularly, acrylic nail gel compositions, and typically employ ultraviolet and/or visible light emitting diodes (“led”) to cure such ultraviolet and/or visible light curable nail gel resins..
|Hydroxyethyl cellulose grafted acrylic latex|
The present invention relates to latex compositions comprising hydroxyethyl cellulose grafted acrylic polymer emulsions and methods for preparing same without gelling or coagulation. The latex composition comprises at least about 0.2% of hec by weight relative to the monomer weight, contains at least about 45% solid, and the average mean volume (mv) latex particle size is in the range of about 320-about 850 nm.
|Water-based polymer emulsions for opaque films and coatings applications on flexible substrates|
A process of preparing a water-based emulsion includes adding a first monomer feed to a reaction vessel in the presence of a first initiator and water to form an acid-functional polymer; neutralizing the acid-functional polymer to form a particulate polymer; and adding a second monomer feed to the reaction vessel in the presence of a second initiator to form an agglomerated polymer; where the process is a one-pot process. The first monomer feed includes a unbranched (meth)acrylate monomer, a (meth)acrylic acid monomer, a branched (meth)acrylate, and a styrenic monomer; the second monomer feed includes a hydrophobic monomer; the water-based emulsion includes the agglomerated polymer; the agglomerated polymer includes the particulate polymer; and the agglomerated polymer having an aggregated drupelet morphology.
