Vinyle Based Polymers

Rigid sometimes abbreviated as rpvc and flexible.

Vinyle based polymers. Poly 4 vinyl pyridine co 2 hydroxyethyl methacrylate random. The majority of polymers in this category consist of vinyl acetate and its copolymers. Poly vinyl acetate is unique in that the most common polymerization method results in a nonlinear highly branched polymer. The glycoside linkages in polysaccharides and the ester groups in polyesters represent points of attack by the enzymes of microorganisms that facilitate their decomposition.

M muthuvinayagam and k sundaramahalingam. Vinyl polymers is a name often used to identify polymers based on the vinyl group nch ch 2 but really has been used to identify polymers and copolymers of vinyl chloride. A vinyl chloride based polymer was obtained by the same method described in example 1 except for adding eugenol and antioxidant to thereby stop polymerization at the time when there was a change of 3 0 kg cm 2 on the basis of the equilibrium pressure at the polymerization temperature inside a polymerization reactor. Pvc comes in two basic forms.

Soil organisms and sunlight than are most petroleum based polymers. Ziegler natta catalyst is a typical commercial catalyst for polyethylene and polypropylene. Such biodegradable materials can be composted broken down and. A 3 4 5 poly vinyl pyridine based random copolymers.

Poly vinyl chloride pvc. Poly vinyl pyrrolidone based polymer blend electrolytes for electrochemical devices. The major families of products fall into. Vinyl acetate monomer is low cost easy to use globally traded and readily available.

Characterization of proton conducting poly ethylene oxide. 5 18 60 61 these polymers have been used extensively in the past for corrosion protective systems but they often need large amounts of strong solvents. Specialty polymers hydrogen containing polymers random and alternating copolymers random copolymers composed of 2 or less different monomers poly vinyl pyridine based random copolymers.

Pvc is the world s third most widely produced synthetic plastic polymer after polyethylene and polypropylene about 40 million tons of pvc are produced each year. Vinyl acetate monomer vam is a critical building block for a number of water based polymers.
