The present disclosure provides novel polyimides having a high aliphatic monomer-content and improved optical properties and solubility relative to conventional polyimides. Also provided are methods of making the polyimides, articles of manufacture incorporating the polyimides and methods for making these, as well as methods of using the polyimides.

Optically transparent polyimides

The present invention relates to conjugated polymers and a method for their synthesis. Furthermore, the present invention relates to electro-synthesis methods for producing polymers that include the use of at least one Lewis acid and at least one proton trap to form organic conjugated polymers having elevated refractive indices. In one embodiment, the present invention relates to an organic polymer having an elevated refractive index, the organic polymer formed by a process comprising the steps of: providing a solution of unsaturated organic monomer units and at least one acidic component; impeding saturation of the unsaturated organic-monomer units by at least one protic element in the solution; and polymerizing the unsaturated organic monomer units to form a conjugated organic polymer having a refractive index of at least about 2.3 for electromagnetic energy having a wavelength of about 700 nm.

Adhesive composition comprises a polyfarnesene and a tackifier. The polyfarnesene can be a farnesene homopolymer derived from a farnesene (e.g., &#x3b1;-farnesene or &#x3b2;-farnesene) or a farnesene interpolymer derived from a farnesene and at least a vinyl monomer. In some embodiments, the at least one vinyl monomer is ethylene, an &#x3b1;-olefin such as styrene, or a substituted or unsubstituted vinyl halide, vinyl ether, acrylonitrile, acrylic ester, methacrylic ester, acrylamide or methacrylamide, or a combination thereof. The composition disclosed herein can be used as a hot melt adhesive, a pressure sensitive adhesive or the like.
