Patent number: 4500683Abstract: A pressure-sensitive adhesive composition containing as a polymer component an addition-polymerization polymer of an acryl-based polymer having sticking properties at room temperature and one or more ethylenically unsaturated monomers capable of forming a homo- or co-polymer having a glass transition point of at least 273.degree. K.; the addition-polymerization polymer is prepared by polymerizing one or more ethylenically unsaturated monomers in the presence of the acryl-based polymer; the present pressure-sensitive adhesive composition has high adhesive strength and cohesive strength.Type: GrantFiled: June 8, 1984Date of Patent: February 19, 1985Assignee: Nitto Electric Industrial Co., Ltd.Inventors: Yutaka Hori, Makoto Sunakawa, Kikuo Takayama, Naoki Matsuoka, Yutaka Moroishi

Patent number: 4487897Abstract: A process for polymerizing acrylic monomers is disclosed. The process involves providing a reactor which is generally in the shape of a screw type reactor having temperature control means thereon. The reactor is continually charged with a supply of acrylic monomers having a viscosity of 10 poises or less at ordinary temperature. The acrylic monomers are continually moved through the reactor by turning of the screw within the reactor in order to cause the acrylic monomers to continually contact renewed surfaces within the reactor. The temperature in the reactor is controlled within two or more zones within the reactor in order to increase the viscosity of the acrylic monomers in the reactor by rapid polymerization within an initial area and then allow polymerization to proceed to one or more additional areas in the reactor to a prescribed rate of conversion. Polymerized product is continuously removed from the reactor.Type: GrantFiled: February 18, 1983Date of Patent: December 11, 1984Assignee: Nitto Electric Industrial Co., Ltd.Inventors: Naoki Matsuoka, Hiroshi Matsumoto, Yutaka Hori, Yoshio Miki, Kenji Sano, Ichiro Ijichi
