IPC: C08F6/06
Filed: 1983-09-27
Abstract: PURPOSE:To recover monomers, etc., without contamination and to thereby reduce the manufacturing cost, by forming an ethylene (co)polymer by using a co- ordiantion polymerization catalyst and deactivating the catalyst with a specified ester compound. CONSTITUTION:Use is made of, as a catalyst deactivator, an ester compound of the formula (wherein R<1>, R<2>, and R<3> are each a 1-20C hydrocarbon group), e.g., diisopropyl phthalate. Namely, ethylene (alone or together with a 3-18C alpha-olefin) is polymerized at an average polymerization temperature >=130 deg.C by using a co-ordination catalyst containing a transition metal compound (e.g., titanium chloride) and an organometallic compound (e.g., organoaluminum compound), the above catalyst deactivator in an amount about 0.1-6 times the total number of moles of the transition metal compound and the organometallic compound is added to the formed polymer mixture, and unreacted monomers and the solvent are recovered. At the same time, the polymer is recovered.

Abstract: PURPOSE:To make unbalanced winding distribution symmetrical with respect to an X or Y axis and thereby facilitate deformation correction from the outside by constructing a deflecting coil consisting of a pair of coils wound in the opposite direction with each other. CONSTITUTION:One of a pair of horizontal or vertical coil is first formed by winding an elementary wire in a gap of the saddle former of a reel in the order of 1 2 3 4 5 (corresponding to 1)  2 ... as shown in a drawing (A). Then, the other coil is formed by winding a wire in the gap of the saddle former of a reel in the quite opposite direction in the order of 1' 2' 3' 4' 5' (corresponding to 1')  2' ... With such constitution, if a dense part of the winding distribution is assumed to be formed, e.g., on the left side of the one of the coils, the other coil forms its dense part at the same part on the right side thereof, allowing the dense parts La of the winding distributions of the coils 10 and 11 to be symmetrically positioned with respect to an X axis. Accordingly, it is possible to make symmetrical winding distribution error with respect to the X axis or a Y axis, allowing distortion correction from the outside to be facilitated.
