Polyester Vinyl Monomer

The material has a thickness of 58 μm and a glossy finish.

Polyester vinyl monomer. Free radical producing compounds such as peroxides. The name is also used for any compound containing that group namely r ch ch2 where r is any other group of atoms. The most widely used member of the category is vinyl acetate. Styrene or a similar vinyl type monomer is used to cross link the resin and form the film.

In chemistry vinyl or ethenyl 1 abbreviated as vi 2 is the functional group with the formula ch ch2. 23 n0 11 pp 921 922 1987 0014 3057 87 3 00 0 00 printed in great britain pergamon journals ltd synthesis of polyester poly vinyl monomer block copolymers by c i simionescu. An industrially important example is. For vinyl adhesives we use a white vinyl monomer.

Vinyl esters undergo homopolymerization via a radical mechanism. The basic acrylic monomers or oligomers contain unsaturated double bonds vinyl groups and consequently cure by addition polymerization involving a free radical reaction. The polyester stickers are better than the paper ones and they are the perfect solution if you are looking for an alternative as a middle ground between the vinyl stickers and other kinds. The resultant polymer can vary from a high viscosity liquid brittle to a low melt solid material.

A laminate comprising a layer of a synthetic linear polyester a plasticizer free primer coating applied to at least one surface of the polyester layer and comprising a cross linked composition. The polymer is then dissolved in a liquid reactive vinyl 1 2 ethylenically unsaturated monomer such as styrene vinyl toluene diallyl phthalate or methyl methacrylate to give a solution with a viscosity in the range between 2 0 and 20 0 poise. Vinyl acetate is not as hydrolytically stable in polymers as are the structurally similar acrylic esters. Unsaturated polyester any of a group of thermosetting resins produced by dissolving a low molecular weight unsaturated polyester in a vinyl monomer and then copolymerizing the two to form a hard durable plastic material.
