    摘要: An oil-resistant agent containing a modified natural product which is a bio-based compound having at least one carboxyl group and in which a hydroxyl group of a carboxyl group is substituted with an R group, or a carboxyl group is substituted with an Ra group.



    R group: —X—R1 or —X-D-X′—R1.
    Ra group:








    wherein X is a direct bond, —O—, —NR11—, or —S—, and R1 is a hydrocarbon group having 1-40 carbon atoms, or a polysiloxane, D is an alkylene group having 1-10 carbon atoms, X′ is —C(═O)—O—, —O—(═O)—, —C(═O)—NR12—, or —NR12—C(═O)— (where, R11 and R12 are each hydrogen or an alkyl group having 1-40 carbon atoms). Also disclosed is a textile product, an oil-resistant paper, a food packaging material or a food container each including the oil-resistant agent, as well as a method of treating paper with the oil-resistant agent.

    摘要: A semiconductor processing system includes a first component forming a first chamber. A first sealed environment in the first chamber is at a first state prior to a door being opened. A load port structure is disposed between the first component and a second component. The load port structure includes walls disposed around an opening of the load port structure. The load port structure is separate from the first component and the second component. A third component is configured to change at least one of the first state of the first sealed environment within the first chamber or a second state of a second sealed environment within a second chamber formed by the second component to cause the first state and the second state to be substantially similar before the door between the first sealed environment and the second sealed environment is opened.
