    Abstract: A process for producing a modified olefin polymer includes the steps of: (1) blending 100 parts by weight of an olefin polymer, 0.01 to 20 parts by weight of a polar group-carrying unsaturated compound, and 0.001 to 20 parts by weight of an organic peroxide, with one another, in a continuous extruder at a temperature T1 for a time S1, thereby forming a first blend; (2) blending the first blend in the continuous extruder at a temperature T2 for a time S2, thereby forming a second blend; and (3) blending the second blend in the continuous extruder at a temperature T3 for a time S3. T1, T2 and T3 have specific relationships to decomposition temperatures of the organic peroxide, and S1, S2 and S3 have specific relationships to half-lives of the organic peroxide.

    Abstract: In a plate exchange apparatus for a rotary press, a plate winding rod is pivotally fitted in a winding rod hole in an outer circumferential portion of a plate cylinder and has a spring groove extending almost an entire length thereof. A plurality of leaf springs are provided in the spring groove. Each leaf spring is constituted by a leaf spring member to have a U-shaped section, and has an end formed with a press portion to urge a leading end of a plate against a surface of a gap of the plate cylinder and the other end formed with a bent portion to catch a bent end wound on a circumferential surface of the plate cylinder. A biasing member biases the plate winding rod in a predetermined rotational direction. A plate winding rod pivoting unit is coupled to an end portion of the plate winding rod by a cam mechanism. A plate press roller extends in an axial direction of the plate cylinder close to the circumferential surface of the plate cylinder, and is moved forward and backward toward and away from the leading end of the plate by a driving unit. A control unit operates the plate winding rod, the plurality of leaf springs, the biasing member, the plate winding rod pivoting unit, and the plate press roller at predetermined timings.
