Abstract
Description
[Technical Field]
[0001] (CROSS-REFERENCE TO RELATED APPLICATIONS) This application claims the benefit of U.S. Provisional Application No. 63 / 384,347, filed November 18, 2022, which is incorporated herein by reference in its entirety.
[0002] The subject matter of this disclosure relates to methods for preparing polymers and pressure-sensitive adhesives having novel architectures characterized by long chain branching. The subject matter of this disclosure also relates to pressure-sensitive adhesives formed from the methods. Additionally, the subject matter of this disclosure relates to tapes and other articles employing the pressure-sensitive adhesives. [Background technology]
[0003] Solvent-based acrylic pressure-sensitive adhesives (PSAs) are used in high-performance applications because they offer a good balance of peel adhesion and cohesive strength. The polymers that make up these adhesives typically have high molecular weights, and the adhesives are characterized by high relative viscosities. Therefore, to make the polymers coatable at ambient temperatures, they must be diluted with a solvent. They are typically coated at 30-40% solids by weight. The solvent is removed (evaporated) immediately after the coating process.
[0004] The lower the solids content of a solvent-based adhesive, the longer it takes for the solvent to evaporate (or drive off) after coating. Therefore, to achieve a solvent-free coating without defects such as bubbles or skinning, very slow line speeds must be used during the coating process. As a result, the manufacturing costs of solvent-based acrylic products are high.
[0005] Acrylic hot melt or warm melt adhesives were developed to rival the adhesive performance of solvent-based adhesives while lowering coating costs by increasing line speeds. The molecular weight of these adhesives must be lower than traditional solvent-based acrylics to ensure the adhesive's viscosity (at 100% solids content) remains in a processable range. This low molecular weight leads to poor cohesion, as evidenced by poor shear performance. Therefore, the adhesive must be crosslinked after coating. Unfortunately, excessive crosslinking reduces the adhesive's peel and tack properties.
[0006] There is a continuing need for polymers that can be prepared for use in a variety of applications over a wide molecular weight range, such as, but not limited to, high molecular weight, high performance PSAs with an excellent balance of peel adhesion and cohesive strength, as well as compositions that can be rapidly coated and crosslinked to form such PSAs, particularly compositions that can be coated both as hot or warm melts and as high solids content coatings.

Log-log Mark-Houwink-Sakurada plots were evaluated using linear regression correlation to observe uniform polymer chain structure.

[0137] Pressure Sensitive Adhesion Test
[0138] To evaluate pressure-sensitive adhesive performance, each polymer solution was applied to a 50 micron thick MYLAR® release liner at a dry coating weight of 55 g / m 2 (g / m²), dried at 120°C for 5 minutes, and UV-C dose 10-13mJ / cm 2 After crosslinking with , the film was transferred to a 2 mil thick MYLAR® film.
[0139] 180° peel adhesion values were measured on stainless steel panels after a given hold time (i.e., 20 minutes or 24 hours) at a crosshead speed of 12 inches / minute (measured in lb / inch). Static shear values (i.e., time to failure in minutes) were also measured on stainless steel panels at room temperature using a 1000 g load with a 1 inch x 1 inch contact area. All tests were conducted in a controlled environment at 22°C and 50% relative humidity.
