20210371575 | Novel Polymers Depolymerizable by Metathesis of a Cleavable Unit - Novel polymers are depolymerizable by metathesis of a cleavable unit. As an example, a series of linear and crosslinked polyurethanes were prepared that can be selectively depolymerized under mild conditions. Two unique polyols were synthesized bearing unsaturated units in a configuration designed to favor ring-closing metathesis to five- and six-membered cycloalkenes. These polyols were co-polymerized with toluene diisocyanate to generate linear polyurethanes and trifunctional hexamethylene- and diphenylmethane-based isocyanates to generate crosslinked polyurethanes. The polyol design is such that the ring-closing metathesis reaction cleaves the backbone of the polymer chain. Upon exposure to dilute solutions of Grubbs' catalyst under ambient conditions, the polyurethanes were rapidly depolymerized to low molecular weight, soluble products bearing vinyl and cycloalkene functionalities. These functionalities enabled further re-polymerization by traditional strategies for polymerization of double bonds. This general approach can be expanded to develop a range of chemically recyclable condensation polymers that are readily depolymerized by orthogonal metathesis chemistry. | 2021-12-02 |

The first amino-functional silane can be a polyamino-functional silane having at least two amino groups and a silane group in which at least one of the amino groups and the silane group are connected by an organic linking group. The composition can include a photoluminescent compound exhibiting photoluminescence at an excitation wavelength above 400 nanometers. Use of the composition as an adhesion promoter and a method including applying the composition to a substrate surface are also disclosed. | 2021-12-02 |
