Abstract
An acrylic composition, or star acrylic polymer, includes the reaction product of an initiator, a first compound, and a highly-branched, polyfunctional core molecule. The initiator has a radical-forming portion and a functional group. The first compound, which includes a vinyl functional group, is reactive with the initiator to form a functionalized intermediate. The core molecule is reactive with the functionalized intermediate to form the acrylic composition. A method of forming the acrylic composition via free-radical polymerization includes the steps of reacting the initiator and the first compound to form the functionalized intermediate, and reacting the core molecule with the functionalized intermediate to form the acrylic composition.
Claims45
An acrylic composition comprising the reaction product of:
- (A) an initiator having a radical-forming portion and a functional group;
- (B) a first compound having a vinyl functional group reactive with said initiator to form a functionalized intermediate;
- and
- (C) a highly branched, polyfunctional core molecule reactive with said functionalized intermediate to form said acrylic composition.
A method of forming an acrylic composition via free-radical polymerization, said method comprising the steps of:
- reacting an initiator having a radical-forming portion and a functional group with a first compound having a vinyl functional group to form a functionalized intermediate with the functional group of the initiator remaining unreacted in the functionalized intermediate;
- reacting a highly branched, polyfunctional core molecule with the functionalized intermediate to form the acrylic composition.
A method of forming a star acrylic polymer having a core and a plurality of functionalized acrylate branches, said method comprising the steps of:
- forming the functionalized acrylate branches from an initiator and a first compound reactive with the initiator;
- condensing the core with the functionalized acrylate branches to form the star acrylic polymer.
