The present invention relates to a melt processable copolyetheramide made by reacting (a) one or more segments of polyamide hard blocks derived from a lactam-terminated diisocyanate and a lactam monomer, and (b) one or more segments of polyether soft blocks derived from a polyether diol. The invention further provides for methods of making said copolyetheramide, including a continuous extruder method of production.

An electrostatic multicolor imaging system employs a transfer surface which is charged imagewise such that blended microcapsular chromogenic photohardenable toner particles are electrostatically deposited only in those charged regions of a latent image formed on the surface where colors are to be provided for the image.

A positive or negative latent image can be developed with negatively or positively charged toner particles, respectively, that are microcapsular. The shell material of the toner particles is a melamine-formaldehyde resin or a starch-based material. The core is a liquid solution comprising at least a liquid, ethylenically unsaturated monomer, a leuco dye and a photoinitiator.

An electrostatic method is disclosed for providing multicolor imaging from a single toner bath. The toner bath is a blend of individual toners, each of which contains a color precursor different from the others. Also disclosed is a method for the double encapsulation of toner particles to produce toner particles characterized by multiple encapsulation.

The disclosed technology provides thermoplastic polyurethane compositions having non-leaching antimicrobial properties while still maintaining good physical properties, methods of making the same, and articles, including medical devices, made from such compositions. The disclosed technology includes a process of making an antimicrobial polymer composition, where the process includes mixing an antimicrobial additive into a polymeric material; wherein said polymeric material comprises a polymeric backbone made up of urethane linkages derived from a polyisocyanate and a polyol; and wherein said mixing occurs under conditions that result in the breaking of a minority of said urethane bonds resulting in reactive isocyanate groups; and wherein two or more of said reactive isocyanate groups react with said antimicrobial additive to covalently bond said antimicrobial additive into the polymeric backbone of said polymeric material; resulting in an antimicrobial polymer composition.

The polymer compositions described herein include the reaction product obtained from a mixture that includes: (i) a hydroxyl terminated intermediate containing at least one furan functional group; and (ii) a polyisocyanate component. The polymer compositions may further include a polymaleimide compound which may be (a) added as a component of the polymer composition, (b) incorporated into the structure of the hydroxyl terminated intermediate containing at least one furan functional group, or (c) both. The resulting polymer composition is capable of thermally reversible crosslinking. Also described are processes for making such polymer compositions, methods of reversibly increasing and/or decreasing the amount of crosslinking in a polymer composition thermally, through utilization of the Diels-Alder cycloaddition mechanism between furan functional groups and the polymaleimide compound, and methods of using the described furan functional group containing materials to prepare polymer compositions capable of thermally reversible crosslinking.

The present invention relates to articles made from thermoplastic polyurethane (TPU) compositions that have crystalline chain ends. The TPU compositions used to make the articles of the invention can provide reduced stickiness and/or tackiness, while maintaining other desirable physical properties, leading to significantly improved handling and processability.
