Abstract

DC60 (24/04/41) This invention provides a granulated diacetal mixture. Containing (a) diacetal powder, such as 1,32,4-bis-0- (Ben Cylidine-D-sorbitol Or the products replaced at the nucleus; and (b) the coupling agent, the granular diacetic mixture prepared by Stirring mixtures containing powder, diacetyl substrate and coupling agent at an equal or high temperature. Than the melting point or softening point of the coupling agent and below the diacetal melting point, casting the resulting compound into pellets or by grinding the resulting pellets. By casting the above into powder, the diacetyl particles in the granular diacetal mixture are connected to each other by a bonding agent. And bulk binders, binders in granulated diacetal mixtures The coated part One or all of the surface of each diacetal particle or its adherence to part or all of the surface of each diacetal particle and the process of the preparation of this mixture, as well as the resin mixtures that can be obtained. From granular and polyolefin resin mixtures, and molded articles obtained from resin mixtures The invention provides a granular mix of diacetyl. Containing (a) diacetal powder such as 1,3: 2,4-bis-0- (Ben Cylidine-D-sorbitol Or the products replaced at the nucleus; and (b) the coupling agent, the granular diacetic mixture prepared by Stirring mixtures containing powders, diacetales and binders At temperatures that are equal to or high Than the melting point or the softening point of the coupling agent and below the melting point of diacetal, casting the resulting compound into granules or by grinding the granules obtained by casting the above into powder, diacetas particles. L in the mixtures diacetal That is granular Connected with each other by mounting connectors. And bulk binders, binders in diacetic mixtures That is granular The coated part One or all of the surface of each particle of diacetic Or adhesion to part or all of the surface of each diacetal particle and the preparation process of this mixture, as well as resin mixtures that can be obtained from granulated diacetyl mixtures and Polyolefin resins, and forgings derived from resin mixtures: Drug Patents
