Title:
CELLULOSE-CONTAINING RESIN COMPOSITION AND CELLULOSIC INGREDIENT
Document Type and Number:
WIPO Patent Application WO/2018/123150
Kind Code:
A1
Abstract:
The present invention relates to: a resin composition which shows satisfactory flowability and mechanical properties; a cellulosic ingredient which gives the resin composition; and resin pellets and a molded resin object which are formed from the resin composition. One embodiment of the resin composition comprises a thermoplastic resin and a cellulosic component, wherein the cellulosic component comprises cellulose whiskers and cellulose fibers. Another embodiment of the resin composition comprises a thermoplastic resin and a cellulosic component, has a coefficient of variation of linear expansion coefficient of 15% or less and a coefficient of variation of tensile rupture strength of 10% or less. One embodiment of the cellulosic ingredient comprises cellulose particles and an organic component. A still another embodiment of the resin composition comprises a thermoplastic resin, cellulose particles, an organic component, and a surfactant. In a further embodiment, the organic component has a static surface tension of 20 mN/m or higher and a higher boiling point than water.
