Latest Patents

Kawasaki's latest patents focus on innovative cellulose acetate resin compositions. One notable invention describes a cellulose acetate composition, which includes a cellulose acetate with a total degree of acetyl substitution ranging from 1.9 to 2.6, combined with a carefully selected plasticizer. The composition specifies that the cellulose acetate should have a number average molecular weight of at least 45,000 and a weight average molecular weight of at least 70,000. The plasticizers involved can be ether-based, featuring at least one terminal hydroxyl group of a polyalkylene glycol etherified, or ester-based, where at least one terminal hydroxyl group is esterified. Both types of plasticizers avoid aromatic rings in the terminal group and are designed for improved functionality.

Another relevant patent elaborates on a cellulose acetate resin composition that combines cellulose acetate with fillers and various types of plasticizers. This formulation includes a cellulose acetate (A) with a total degree of acetyl substitution of 2.60 or less, a filler (B) such as inorganic compounds or cellulose, and a plasticizer (C) primarily comprising glycerin esters, ether-based, or glycol esters. The proportions of components A, B, and C are carefully defined to ensure optimal performance, making this composition a significant development in the realm of materials technology.
