PROCESS FOR DISPERSING CELLULOSE ESTERS INTO ELASTOMERIC COMPOSITIONS

摘要

In one embodiment of the present invention, a cellulose ester concentrate is provided. The cellulose ester concentrate comprises at least one non-nitrile carrier elastomer and at least one non-fibril cellulose ester. The Tg of the cellulose ester is greater than the Tg of the carrier elastomer. The cellulose ester concentrate comprises at least 15 weight percent of the cellulose ester. In another embodiment of the present invention, a process to produce a cellulose ester concentrate is provided. The process comprises mixing at least one cellulose ester with one or more carrier elastomers to produce the cellulose ester concentrate. At least a portion of the mixing occurs at a temperature that exceeds the Tg of the cellulose ester.
