Abstract: An agent for suppressing pollen dispersal, containing an oleic acid derivative or a linoleic acid derivative as an active ingredient, which does not influence the trunk, branches and leaves of trees, shows a sharp efficacy on the male organ and is in the form of a solution or emulsion having solution stability by diluting with water.

Abstract: The invention provides a herbicidal composition containing, as an active ingredient, glycerol fatty acid ester obtained from fatty acid having an even-numbered carbon number of 6-12 and glycerol.

Abstract: A novel polydialkylsiloxane/polyamide copolymer which is excellent in biocompatibility, mechanical strength, and heat moldability, applicable for use in medical materials, ophthalmic materials, cosmetics, and electronic materials, and has a main chain represented by the formula (4), one end represented by the formula (5) and another end represented by the formula (6): —(NH—A—NHCO—B—CO)m—  (4) —NH—A—NH—X2  (5) —X1  (6) wherein the ratio of —R1—(Si(R2) (R3)—O)n1-Si(R2) (R3)—R1— as A to the divalent organic group having 1 to 20 carbon atoms as A is within the range of 1:0.01˜100, and the proportion of X1 and X2 being hydrogen atoms is 10% or less relative to all the end groups, a process for producing the same, and a variety of its uses.

Abstract: Solubilizers, emulsifiers and dispersing agents having the effects of moisturizing the skin when used as washing agents and having the character of elevating the concentration of a material to be solubilized, emulsified or dispersed in solvents including water as compared with the case where the material is employed alone, or elevating the apparent concentration of a material to be emulsified or dispersed in solvents by increasing homogeneity of the emulsion or dispersion which contain as the active ingredient polymers obtained by polymerizing monomer compositions containing at least one hydrophilic monomer (a) having a group represented by general formula (1) in the side chain, wherein R1, R2 and R3 represent each H or C1-4 alkyl.

Abstract: A high molecular material and a medical material which is a mixed material containing a copolymer A produced by copolymerization of a monomer composition containing a monomer having a side chain represented by the formula (1) ##STR1## (R.sup.1, R.sup.2, R.sup.3 ; H or a C1-4 alkyl group) and a hydrophobic monomer, and one or more sorts of hydrophobic polymer B other than the copolymer A; wherein structure of said mixed material shows phase separation in which domains of several hundred micrometers or less in size consisting of the copolymer A are uniformly distributed in a phase consisting of said hydrophobic polymer B. A liquid high molecular composition in which the copolymer A and the hydrophobic polymer B are dissolved in a mixed solvent consisting of a halogenated hydrocarbon solvent and a lower alcohol solvent, which has turbidity of 60% or less.

Abstract: The present invention provides a polymer complex of a sugar response type having boronic acid groups in the polymer. Medicines may be contained or linked, preferably, the medicines have hydroxy groups. The polymer having boronic acid groups and the medicine having hydroxy groups may be linked by boronic acid ester bonds. The complex may also comprises polymers having boronic acid groups and polymers having hydroxy groups, and these polymers may be cross-linked.
