What is ethylene acid copolymer?
Ethylene acrylic acid copolymer (EAA) is used for adhesion to unprimed foil, paper, and metallized film and provides substrate protection for improved structure reliability and barrier integrity.

What is Nucrel?
NUCREL™ AE is a terpolymer of ethylene, methacrylic acid, and acrylate. It is available for use in conventional extrusion coating, coextrusion coating, and extrusion laminating equipment designed to process polyethylene resins.
What is glyceryl acrylate acrylic acid copolymer?
Glyceryl acrylate/acrylic acid copolymer is the fancy word for a common polymer (big molecule from repeated subunits), namely polyacrylic acid (aka carbomer when it comes to cosmetics) with glycerin attached to it in some places.
What is an ionomer resin?
A transparent, electrically conductive, Thermoplastic polymer. Ionomer resins are primarily composed of ethylene copolymerized with small amounts of vinyl and acid (such as methacrylic acid) groups. Ionomers crosslink to form a plastic that is resistant to abrasion, breaking, and chemicals.
What is methacrylic acid copolymer used for?
It is a solid white powder with dissolution above pH of 5.5, and is used in enteric coatings for fast dissolution in the upper bowel, for granulation of drug substances in powder form for controlled-release, and for site-specific drug delivery. It is typically released in the duodenum of the gastrointestinal tract.
What are the 2 functional groups in acrylic acid?
Acrylic acid (2-propanoic acid, C3H4O2), (Figure 24) is the simplest unsaturated carboxylic acid. It has both a double bond and a carboxyl group linked to its C3, and these two functional groups enable its polymerization.
Does acrylic oxidize?
Oxidation: Acrylic headlights oxidize when exposed to UV light. Headlight lenses come with a clear top coat to help prevent this, but eventually, the coating wears off, and sunlight turns the hard plastic yellow.
What is ethylene methacrylic acid?
Copolymers of ethylene and methacrylic acid or acrylic acid. These are highly polar, functional copolymers that offer flexibility and excellent adhesion to a variety of substrates. Most often used in blow film, extrusion coating and lamination.
What is ethylene acrylic acid?
Ethylene/Acrylic Acid Copolymer is a synthetic polymer used as a binder and film-former in dyes, adhesives and recently, skin creams.
