ABSTRACT:
An oilfield element or assembly having a polymeric substrate protected by a polymeric coating adhered to at least a portion of the polymeric substrate. The coating includes a polymer having the formula —[R(R1x)(R2y)]—, wherein: R is selected from C—C, aryl, or —C(R3p)(R4q)-aryl-C(R5r)(R6s)—; R1and R2may be the same or different; R3, R4, R5, and R6are independently selected from halogen atoms and hydrogen atoms; and n is an integer ranging from 10 to 10,000.
