    Abstract: PROBLEM TO BE SOLVED: To obtain a polymeric compound for photoresist excellent in resist properties such as alkali solubility and adhesion to a substrate, especially, excellent in adhesion to a substrate. SOLUTION: The photoresist polymeric compound comprises a vinyl polymer obtained by a polymerization reaction using a polymerization initiator containing an oxygen-containing group or a substituted or unsubstituted amino group in the molecule. The polymerization initiator used is exemplified by an azoic radical polymerization initiator. Examples of the oxygen-containing groups include hydroxyl, carboxyl, substituted oxy, substituted oxycarbonyl, acyls, substituted or unsubstituted carbamoyl, hydroxyimino, substituted oxyimino, and nitro. The vinyl polymer is exemplified by a homo- or co-polymer of a (meth)acrylic monomer, or a copolymer of a (meth)acrylic monomer with other monomers.

    Abstract: PROBLEM TO BE SOLVED: To prepare a rubber-modified styrenic resin having a high impact resistance. SOLUTION: The preparation process uses a continuous reaction apparatus which is successively equipped with three complete-mixing type reactors and one tower type reactor. The process comprises a step wherein the whole amount of styrenic monomers used for preparing a rubber-modified styrenic monomer is divided into three batches at a desired ratio, and then the first batch of styrene monomers and the whole amount of rubbers, which make 100 wt.% in total, are introduced into a first reactor and subjected to initial polymerization, a step wherein a polymerized liquid obtained in the first reactor and the next batch of styrenic monomers are introduced into a second reactor and polymerized under stirring until a rubber phase inversion occurs to yield a rubbery polymer as dispersed particles, and a step wherein a polymerized liquid obtained in the second reactor and the last batch of styrenic monomers are continuously introduced into a third reactor to increase the polymerization conversion rate.

    Abstract: PROBLEM TO BE SOLVED: To obtain a catalyst for the production of a poly-α-olefin having a low atactic component and highly stereoregular isotactic component by impregnating a magnesium halide with an organometallic compound and forming only a recemic modification structure of a zirconium metallocene compound on its surface. SOLUTION: The organometallic compound used is a compound of formula I (wherein R and R are each an organic liquid such as cyclopentadienyl, indenyl, fluorenyl or a derivative thereof; M is a group IVB transition metal; and X is a halogen). This is reacted with a halide of a group IVA metal (M ) to obtain a compound represented by formula II (wherein M is an element typified by a group IVB element; R and R are each as defined in formula I; M is a group IVA transition metal element; and X and X are each a halogen). A magnesium halide is impregnated with the organometallic compound of formula II to obtain a catalyst for the production of a poly-α-olefin. This is combined with a promoter such as a water-modified organoaluminum compound of a trialkylaluminum compound of formula IV (wherein R is a 1-10C alkyl).
