Polyvinyl ether

One class of materials with some inherent PSA properties includes polyvinyl-ethers. Vinyl ether monomers are industrially derived from the reaction of acetylene with alcohols [117]. The most common alcohols used are methanol, ethanol or isobutanol. A generic structure of the vinyl ether is shown below ... [Pg.509]

This type of plasticization is important and several groups of polymers have been suggested for this method polymer hydrocarbons polymer halogen-containing hydrocarbons polymers containing ester groups polyvinyl ethers and acetals, and some other polymers of different constitution. [Pg.97]

The good solubility of the polyvinyl ethers in polar and nonpclar solvents was useful for the combination with nitrocellulose, whereby the water solubility of the polyvinylmethyl ether has no influence. Polyvinyl ethers have low compatibility with many polymers and therefore are mostly combined with other compatible plasticizers. As they are nontoxic they can be used in food packaging. [Pg.99]

The phenoxy resins can also be plasticized with many of the common plasticizers and still maintain a high percentage of strength, while the bonding temperature is substantially reduced. An effective hot-melt adhesive is one in which polyvinyl ether is blended into the phenoxy resin. [Pg.253]

For the investigations reported here polyvinyl alcohol (PVA) and its derivatives such as polyvinyl acetate, polyvinyl ether etc. were used as the basic polymeric materials. These compounds can easily be converted into polymeric analogues [1]. It was shown in an earlier work [2] that PVA-membranes with an asymmetrical structure can be obtained by phase-inverted precipitation similar to the method of Loeb and Sourirajan [3]. These membranes can also be rendered inso].uble in water by... [Pg.281]

Attempts have been made over time to improve the physical properties of novolacs. The use of phenol formaldehyde resins prepared in alkaline medium in photoresist compositions is mentioned in a Kalle Co. AG patent. The use of polyvinyl ethers in combination with novolacs to impart stickiness and plasticization action to the latter was patented by Christensen. Steinhoff, Isaacson, and Roelants of the Shipley Company mention the use of vinyl ethers in a patent on roller coating. Lower alkyl polyvinyl ethers, such as methyl, ethyl, butyl, and isobutyl, are added to novolac resins to improve coating flexibility and adhesion to metal surfaces as well as to improve resistance to mildly alkaline solutions. The use of styrene, methyl styrene, and styrene-maleic anhydride copolymers in combination with novolac was mentioned in several patents of both Shipley and Kalle Co. AG. When novolac is copolymerized with maleic anhydride, a resin that is readily soluble in alkaline solutions is obtained. ... [Pg.304]
