Polyester Vinyl Monomer

The resultant polymer can vary from a high viscosity liquid brittle to a low melt solid material.

Polyester vinyl monomer.

Free radical producing compounds such as peroxides. 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. 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. 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. 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. The basic acrylic monomers or oligomers contain unsaturated double bonds vinyl groups and consequently cure by addition polymerization involving a free radical reaction. For vinyl adhesives we use a white vinyl monomer.

In chemistry vinyl or ethenyl 1 abbreviated as vi 2 is the functional group with the formula ch ch2. Vinyl esters undergo homopolymerization via a radical mechanism. The most widely used member of the category is vinyl acetate. The name is also used for any compound containing that group namely r ch ch2 where r is any other group of atoms.

E comanita v received 7 july 1987 abstract polycondensations were carried out between succinyl chloride 4 4 azobis 4 cyanovaleryl chloride and bisphenol a to yield copolyesters containing labile n n units. 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. Styrene or a similar vinyl type monomer is used to cross link the resin and form the film. It is the ethylene iupac ethene molecule h2c ch2 with one fewer hydrogen atom.
