    摘要: The present invention concerns compounds of Formula I R24-zSi[(Q)xA(CH2)yH]z or of Formula II [H(CH2)yA(Q)x]bSiR13-bSiR13-b[(Q)xA(CH2)yH]b, wherein Q is OCH2CH2, OCH2CHCH2, or any combination of one or more units of OCH2CH2 and OCH2CHCH2; A is O, OC6H4, S, NH, NR, O—C(O)—; R is alkyl, aryl, or alkaryl; x is greater than 2 and less than 100;y is greater than 0; except when A═OC6H4, then y is greater than or equal to 0; z is 1 to 4; and each R2 is independently selected from the group consisting of alkyl, aryl and alkaryl; B is O, C6H4, —(CH2)q—, and hydrocarbylene; q is greater than 1 and less than 30; b is 1 to 3; and each R1 is independently selected from the group consisting of alkyl, aryl, and alkaryl, used as nonvolatile in situ precursors to anti-fog agents for packaging films and a novel process of making such films.
