Abstract
A (meth)acrylated hyperbranched polymer consists of C, H, Si, optionally O, and optionally F atoms. The (meth)acrylated hyperbranched polymer comprises end groups, and at least some of the end groups comprise (meth)acryloyloxy groups. A method of making and a curable composition including the (meth)acrylated hyperbranched polymer are also disclosed. An electronic device includes an at least partially cured form of curable composition.

A (meth)acrylated hyperbranched polymer consisting of C, H, Si, optionally O, and optionally F atoms, wherein the (meth)acrylated hyperbranched polymer comprises end groups, and wherein at least some of the end groups comprise (meth)acryloyloxy groups.
A method of making a hyperbranched polymer, the method comprising:
- i) forming a hyperbranched polymer by combining first components comprising:
- a) at least one first monomer component independently having p Si—H groups and consisting of C, H, Si, optionally O, and optionally F atoms, wherein each p is independently an integer greater than or equal to 2;
- b) at least one second monomer component independently having q vinyl groups and consisting of C, H, optionally Si, optionally O atoms, and optionally F atoms, wherein each q is independently an integer greater than or equal to 2, wherein p/q is at least 2.1 to form a hyperbranched polymer;
- c) at least one hydrosilylation reaction catalyst;
- and
- ii) endcapping the hyperbranched polymer with at least one primary alkenyl (meth)acrylate.
