摘要:
Provided is a method for producing a diallylamine acetate polymer comprising polymerizing diallylamine acetate in water or a polar solvent in the presence of a radical initiator, the radical initiator being an organic acid addition salt of a specific cyclic amidinoazo compound, and a diallylamine acetate polymer solution free of halogen.

Provided is a process for producing a copolymer of a diallylamine and sulfur dioxide which copolymer has a higher molecular weight and water-solubility than that obtained by a conventional production process by copolymerizing the diallylamine and sulfur dioxide in the presence of an acid and a radical polymerization initiator in a polar solvent.

摘要:
Provided is a process for producing a copolymer of diallyldialkylammonium salt and a maleic acid which copolymer is free of residual monomers and polymerization initiator and hence stably exhibits excellent performances in various uses, and the process comprises polymerizing a monomer mixture comprising diallyldialkylammonium salt and maleic acid in the presence of persulfate as a radical polymerization initiator in water or a polar solvent, and completion of the polymerization-reaction, decomposing the radical polymerization initiator to produce a copolymer comprising diallyldialkylammonium salt constituent unit and a maleic acid constituent unit.

摘要:
A tibia pad has: a right foot placement portion having a right side horizontal portion positioned beneath and rearward of an accelerator pedal on which a passenger's heel who is stepping-on the accelerator pedal is placed, and a right side inclined portion integrally formed with a vehicle front side of the right side horizontal portion and positioned beneath the accelerator pedal; and a rib formed at least at a bottom surface of the right side horizontal portion at the right foot placement portion by a region between a pair of groove portions that are formed so as to extend along a vehicle longitudinal direction and so as to be lined-up in a vehicle transverse direction, and that is provided at a position that is offset toward a vehicle transverse direction one side with respect to a central line that passes-through a vehicle transverse direction central portion of the accelerator pedal.
