Patent ID: 7431969

Claim:
A method of forming a polymer coating on a surface of an article, comprising the steps of: placing said article on a stage in a chemical vapor deposition reactor; wherein said stage is optionally maintained at about a first temperature; mixing together a gaseous monomer at a first partial pressure, a gaseous initiator at a second partial pressure and, optionally, a gaseous crosslinker at a third partial pressure, thereby forming a reactive mixture; and contacting said surface of said article with said reactive mixture; wherein said gaseous initiator is selected from the group consisting of peroxides, hydroperoxides, and diazenes; said gaseous monomer is a compound of formula I; and said gaseous crosslinker is a compound of formula IV: wherein, independently for each occurrence, X is —C(R 2 ) 2 —, —O—, —S— or —N(R 2 )—; A is —O—, —S— or —N(R 2 )—; Y is —(C(R 2 ) 2 ) n —; B is —C(R 2 ) 2 ) m —; Z is R 2 , OR 2 , SR 2 , or N(R 2 ) 2 ; R is —H, —CH 3 , —CH 2 CH 3 , —CH 2 CH 2 CH 3 , —CH(CH 3 ) 2 , —C(CH) 3 , —CH 2 CH 2 CH 2 CH 3 , —CH(CH 3 )CH 2 CH 3 , or —CH 2 CH(CH 3 ) 2 ; R 1 is —H, —CH 3 , —CH 2 CH 3 , —CH 2 CH 2 CH 3 , —CH(CH 3 ) 2 , —C(CH) 3 , —CH 2 CH 2 CH 2 CH 3 , —CH(CH 3 )CH 2 CH 3 , or —CH 2 CH(CH 3 ) 2 ; R 2 is —H, —CH 3 , —CH 2 CH 3 , —CH 2 CH 2 CH 3 , —CH(CH 3 ) 2 , —C(CH) 3 , —CH 2 CH 2 CH 2 CH 3 , —CH(CH 3 )CH 2 CH 3 , —CH 2 CH(CH 3 ) 2 , cycloalkyl, aryl or aralkyl; n is 0 to 6 inclusive; and m is 1 to 6 inclusive.
