Described herein is a pressure sensitive adhesive comprising a high molecular weight fluorinated polymer having a Tg less than about 0&#xb0; C. and a number average molecular weight greater than about 20 kilograms/mole; and a low molecular weight fluorinated polymer derived from an ethylenically unsaturated fluorinated monomer, wherein the low molecular weight fluorinated polymer has a Tg greater than about &#x2212;15&#xb0; C. and a number average molecular weight less than about 18 kilograms/mole. Also described herein are articles comprising the pressure sensitive adhesive composition.

Fluorinated pressure sensitive adhesives and articles thereof

A curable composition comprises a fluorinated polyether represented by the formula: Z&#x2014;Xand a nonfluorinated polyether represented by the formula Q-XZrepresents a p-valent perfluorinated polyether group. Qrepresents a y-valent hydrocarbon polyether group. Each Xand Xgroup independently represents a functional group. p and y are integers &#x2265;2. At least some of the p Xgroups are reactive to at least some of the y Xgroups to form a covalently cross-linked polymer network. Hybrid fluoroelastomers made by curing the curable compositions are also disclosed.
