Abstract: The invention relates to an acrylic impact modifier having a core-shell structure that provides an acrylic impact modifier composition comprising (a) a rubber core containing an alkyl acrylate polymer comprising at least two layers having different cross-linking densities, and (b) a shell containing an alkyl methacrylate polymer; to a process for the preparation of the acrylic impact modifier; and to a poly(vinyl chloride) composition comprising it. The acrylic impact modifier imparting excellent impact resistance was invented by employing multi-stage polymerization and at the same time by controlling the swelling index of rubber particles by changing the degree of cross-linking from stage to stage. And the poly(vinyl chloride) comprising the impact modifier of the present invention has good weatherability as well as excellent impact strength.

Abstract: This invention relates a novel gene which is induced by water deficit and abscisic acid. The gene encodes for a transcription factor, particularly homeodomain-leucine zipper transcription factor which contains a transcriptional activation domain in the C-terminal region and a DNA-binding domain in the N-terminal region. The gene can be cloned into an expression vector to produce a recombinant DNA expression system suitable for insertion into cells to form a transgenic plant transformed with this gene. The gene of this invention can be also used to produce transgenic plants which exhibit enhanced resistance to drought.
