What is vinyl neodecanoate copolymer?

VA/Crotonates Copolymer, also called vinyl acetate/crotonic acid copolymer, is a polymer of vinyl acetate and one or more monomers consisting of crotonic acid or any of its simple esters. It occurs as fine transparent beads. VA/Crotonates Copolymer dries to form a thin coating on the skin, hair, or nails.

What is VeoVa 10?

Vinyl neodecanoate (trade name VeoVa 10) is a vinylic monomer that is virtually always used in combination with other monomers to create lattices or emulsion polymers. The trade name is an acronym of Vinyl ester of Versatic Acid with the number 10 meaning 10 carbons in the molecule.

How do you polymerize vinyl acetate?

Accidental polymerization of recovered vinyl acetate An example of such a process is the manufacture of polyvinyl alcohol by polymerization of vinyl acetate in the presence of methanol initiated by azobisisobutyronitrile (AIBN), followed by alkaline hydrolysis of the polyvinyl ester.

What is vinyl Isodecanoate crosspolymer?

Acrylates/Vinyl Isodecanoate Crosspolymer is a copolymer of the ester of vinyl isodecanoateand one or more monomers of acrylic acid, methacrylic acid or one of their simple esters crosslinked withpolyalkenyl polyether.

What is the trade name for Vinyl neodecanoate?

Vinyl neodecanoate (trade name VeoVa 10) is a vinylic monomer that is virtually always used in combination with other monomers to create lattices or emulsion polymers. The trade name is an acronym of Vinyl ester of Versatic Acid with the number 10 meaning 10 carbons in the molecule. It has a medium to low glass transition temperature of -3 °C.

Which is the monomer in Vinyl neodecanoate homopolymers?

As the monomeric component of vinyl neodecanoate homopolymers and as the comonomer in copolymers manufactured using the monomers listed under the substance heading entitled “”””Polymers: Homopolymers and copolymers of the following monomers”””” in 21 CFR 175.105 (c) (5) and 21 CFR 176.180 (b) (2).

What does the number 10 mean in neodecanoate?

The trade name is an acronym of Vinyl ester of Versatic Acid with the number 10 meaning 10 carbons in the molecule. It has a medium to low glass transition temperature of -3 °C. Chemically, it is a mixture of isomeric vinyl esters of neodecanoic acid .

Why are star copolymers more brittle than regular polystyrene?

In the example cited, the rubbery chains absorb energy when the substance is hit, so it is much less brittle than ordinary polystyrene. The product is called high-impact polystyrene, or HIPS. Star copolymers have several polymer chains connected to a central core.
