Abstract: The present invention is directed to polyester powders suitable for use in 3D printing processes, methods of using such polyester powders in 3D printing processes, and processes for the manufacturing thereof. The polyester powders prepared in accordance with the present invention are easily recycled after such polyester powders have been subjected to 3D printing conditions. In addition, the present invention is directed to recycling processes that recondition waste polyester powders into polyester powders suitable for 3D printing.

Abstract: The present invention relates to the polymeric reaction product of compounds according to Formula (I) and Formulae (II) or (III). Formula (I) has the following structure: where R1, R2, R3 and R4 are independently H, OH, optionally substituted C1-12alkyl, optionally substituted C1-12alkenyl, C1-12aldehyde, C3-12acetals, C2-12 ether, and/or C2-12 ester; where optionally at least one of R1, R2, R3 and R4 is H. Formulae (II) and (III) have the following structure: where X is H or C1-4alkyl; Y is OH or OR5 where R5 is C1-12alkyl, C3-12aryl, C4-12aralkyl or C3-12cycloalkyl; and Z is an electron-withdrawing group.

Abstract: There is disclosed certain hyperbranched polyester amides with a cloud point of at least 50° C. in water with end groups selected from: two or more i] tertiary amine functional end groups ii) ammonium functional end groups, iii) polyalkylene glycol functional end groups; iv) quaternary ammonium zwitterionic end groups and/or v) other ionic groups (such as phosphate or sulfate), that are useful in various end uses such as a flocculant.

Abstract: There is disclosed certain hyperbranched polyester amides with a cloud point of at least 50° C. with end groups selected from: betaine-type end groups useful in various end uses such as a flocculant.

Abstract: There is disclosed use of hyperbranched polyester amides as a foamer to stabilize mixtures of oil and water especially for mixtures found in gas and/or oil wells to facilitate extraction of the well contents.

Abstract: The present invention relates to a method for preparing a branched non dendrimeric macromolecule, comprising: a) providing an addition product of an ?,?-olefinically unsaturated compound and an amine comprising at least two hydroxyl groups; and b) esterifying at least part of the hydroxyl groups of the addition product with an olefinically unsaturated carboxylic acid, an olefinically unsaturated carboxylate anion or an olefinically unsaturated carboxylic acid anhydride. The invention further relates to macromolecules obtainable by a method of the invention.
