Abstract:
Starch esters are made by: reacting a starch with an esterifying agent in the presence of a catalyst in a solvent for the starch ester, the esterifying agent including a mixture of at least two esterifying agents; or pre-treating a starch in a bath being free of an esterifying agent, and reacting the pre-treated starch with an esterifying agent in the presence of a catalyst. Articles are made by blending cellulose ester and starch ester, may be cross-linked, and may include internal plasticizers.
Abstract:
A cellulose ester film comprising a cellulose ester and a compound containing an acrylate group or a methacrylate group; and a phenolic hydroxyl group, in the molecule.
Abstract:
The mixture solvent of dichlorimethane type, the TAC and the plasticizer are supplied into a dissolution tank, and stirred therein with a stirrer to obtain a dispersing solution. The dispersing solution is fed into a storing tank and further stirred therein. Then the dispersing solution is fed by a pump to a heat exchanger for the heating, and thereafter the stirring is made with a static mixer. The temperatures of the dope is measured at many measuring points. On the basis of the temperature distribution, the heat transmission conditions of the heat exchanger are adjusted. Then the dope is fed to a heat exchanger for cooling, to cool to at most the normal boiling point of the dope. Then the mixing is made with a static mixer. Thus the obtained dope is uniform.
Abstract:
An inline mixing device (53) is constituted of a sulzer mixer (160) disposed in an upper stream and a static mixer (170) disposed in a downstream. An additive supplied through an orifice (150a) passes through the sulzer mixer (160) disposed in the upstream. As the sulzer mixer (160) is superior in dividing the flow, the additive is uniformly dispersed in a dope pipe (152). Thereafter, the additive passes through the static mixer (170). As the static mixer (170) is superior in reversing the flow, the additive and the primary dope are further stirred and kneaded. The inline mixing device (53) uses the two different kinds of mixers for effectively mixing the additive and the dope while taking advantages of each mixer.
