This invention provides cellulose ester interpolymers, and methods of oxidizing cellulose interpolymers and cellulose ester interpolymers. The invention also provides routes to access carboxylated cellulose ester derivatives with high acid numbers wherein the carboxyl group is attached directly to the cellulose backbone by a carbon-carbon bond. Through functionalization of an intermediate aldehyde, the corresponding cationic or zwitterionic cellulose ester derivatives can also be accessed. The interpolymers of the present invention have a number of end-use applications, for example, as binder resins in various types of coating compositions and as drug delivery agents.

Cellulose interpolymers and method of oxidation

Cellulose interpolymers and methods of oxidation

A refinish coating composition is provided comprising: a) at least one refinish coating resin; b) at least one solvent; c) at least one pigment; d) optionally, at least one crosslinking agent; e) at least one cellulose mixed ester having a weight average molecular weight (M) greater than 10,000 and f) at least one low molecular weight cellulose mixed ester. In addition, processes for coating the refinish coating composition on a substrate are also provided.

Refinish coating compositions comprising low molecular weight cellulose mixed esters

A basecoat composition is provided comprising: a) at least one film-forming polymer selected from the group consisting of acrylic polyols and polyester polyols; b) at least one rheological modifier; c) at least one solvent; d) at least one pigment; e) optionally, at least one microgel; f) optionally, at least one crosslinking agent; and g) at least one cellulose mixed ester. A wet-on-wet-on wet process is also provided. The process for coating a substrate comprises: a) applying a primer to said substrate to produce a primed substrate; b) applying a basecoat composition to said primed substrate while said primer is wet to produce a basecoated substrate; and c) applying a clearcoat composition to said basecoated substrate while said basecoat composition is wet and optionally said primer is wet to produce a coated substrate. Coated articles are also provided.

Basecoat coating compositions comprising low molecular weight cellulose mixed esters

Cellulose mixed esters are disclosed having low molecular weights and low degrees of polymerization. These new cellulose mixed esters include cellulose acetate propionate and cellulose acetate butyrate. The esters exhibit solubility in a wide range of organic solvents with minimal viscosity increase, are compatible with a wide variety of resins, and are useful in coatings and inks compositions as binder resins and rheology modifiers.

Low molecular weight cellulose mixed esters and their use as low viscosity binders and modifiers in coating compositions

Carboxyalkylcellulose esters are disclosed having relatively low degrees of polymerization. These new carboxyalkylcellulose esters include carboxymethylcellulose acetate, carboxymethylcellulose acetate propionate, and carboxymethylcellulose acetate butyrate. The inventive esters exhibit solubility in a range of organic solvents, and are useful in coatings and ink compositions as binder resins and rheology modifiers.

Low molecular weight carboxyalkylcellulose esters and their use as low viscosity binders and modifiers in coating compositions

The present invention is directed to an apparatus and a method for monitoring the viscoelastic properties, of a liquid film (e.g. coating). The apparatus includes a substrate for supporting a liquid film and a T-bar probe that is partially submerged in the liquid film. The apparatus is designed to be attached to a conventional rheometer equipped with a means for effecting relative movement between the probe and the substrate and means for monitoring the resistance to movement of the probe in contact or partially submerged in the film to obtain a measurement of the solidification properties of the liquid film. This apparatus and method are particularly useful in comparing the effects of film formers, viscosity modifiers, solvents, and minerals on the drying rate of coatings at the early stage of film formation.
