Patent number: 6517910Abstract: In one aspect the invention provides an energy efficient polymerization method comprising irradiating a polymerizable composition and a photoinitiator with a source of essentially monochromatic radiation where the photoinitiator and the wavelength of the radiation source are selected such that the extinction coefficient of the photoinitiator at the peak wavelength of the source is greater than about 1000 M−1 cm−1 and such that the photoinitiator absorbs at least two percent of the actinic radiation incident on the coating. In another aspect the invention provides energy efficient methods of polymerizing polymerizable compositions and crosslinking crosslinkable compositions by irradiating the respective compositions with a low power source of essentially monochromatic radiation.

Patent number: 6436532Abstract: Disclosed is a novel, multi-stage irradiation process for the production of an acrylic-based adhesive or pressure-sensitive adhesive tape. The first irradiation step or stage employs electromagnetic radiation at a relatively low average intensity (i.e., 0.1 to 20 mW/cm2) and the subsequent step employs electromagnetic radiation at a relatively higher average intensity (i.e., greater than 20 mW/cm2.) Also disclosed are acrylic-based psa tape materials made by the novel process.Type: GrantFiled: January 16, 2001Date of Patent: August 20, 2002Assignee: 3M Innovative Properties CompanyInventors: John D.

Patent number: 6174931Abstract: Disclosed is a novel, multi-stage irradiation process for the production of acrylic-based compositions such as adhesives or pressure-sensitive adhesive tapes. The first irradiation step or stage employs electromagnetic radiation at a relatively low average intensity (i.e., 0.1 to 20 mW/cm2) to effect a relatively low extent of monomer conversion, and the subsequent step employs electromagnetic radiation at a relatively higher average intensity (i.e., greater than 20 mW/cm2) to complete the photopolymerization. Also disclosed are acrylic-based psa tape materials made by the novel process.Type: GrantFiled: October 4, 1993Date of Patent: January 16, 2001Assignee: 3M Innovative Properties CompanyInventors: John D.

Patent number: 5867238Abstract: A polymer-dispersed liquid crystal device comprises a multiplicity of droplets of a birefringent, functionally nematic liquid crystal material dispersed in a matrix comprising the reaction product of ultraviolet radiation polymerizable materials. The device specularly transmits incident light as a function of the magnitude of an electric field applied across the device. The difference between a first applied voltage corresponding to a first percentage of the total incident light transmitted by the device as specular light and a second applied voltage corresponding to a second percentage of the total incident light transmitted by the device as specular light is greater than or equal to 15 volts. As a result, a polymer-dispersed liquid crystal device according to the invention displays a variable grey scale which has a uniform optical transmission. A method for preparing a PDLC device in general is also disclosed.Type: GrantFiled: August 19, 1996Date of Patent: February 2, 1999Assignee: Minnesota Mining and Manufacturing CompanyInventors: Stephen A.
