An inhibitor composition contains alkyl thiophosphoric triamide (or a mixture of alkyl thiophosphoric triamide and dicyandiamide), dissolved in a liquid medium comprising at least one organic solvent, at least one amine stabilizer and, optionally, at least one dye and/or at least one odor masking agent, is useful in making fertilizer compositions and in a method of fertilizing target plants.

The present invention relates to stabilizers for thiol-ene compositions and to radiation curable thiol-ene compositions based thereon. Such radiation curable compositions can advantageously be used in inks, overprint varnishes, coatings, adhesives, for the making of 3D objects and for the making of solder resist and gel nails. Provided in particular is an inhibitor system (I) for thiol-ene compositions based on —at least one inhibitor compound (i) having a % DPPH radical scavenging activity of at least 90%, the inhibitor compound (i) being selected from substituted benzene compounds or substituted naphthalene compounds containing at least two substituents selected from the group consisting of hydroxyl groups and C1-C3 alkoxy groups bonded directly to the benzene or the naphthalene ring, —at least one acidic compound (ii) having a pKa between 1 and 3, and —at least one compound (iii) selected from the group consisting of phosphites and phosphonites, with the proviso that if the inhibitor compound (i) is a substituted benzene that it contains at least two hydroxyl groups bonded directly to the benzene ring. Also provided is an inhibitor system (II) for thiol-ene compositions based on that is based on —at least one inhibitor compound (i) having a % DPPH radical scavenging activity of at least 90%, the inhibitor compound (i) being selected from substituted benzene compounds or substituted naphthalene compounds containing at least two substituents selected from the group consisting of hydroxyl groups and C1-C3 alkoxy groups bonded directly to the benzene or the naphthalene ring, —at least one compound (iv) selected from the group consisting of spirophosphites, and —optionally, at least one acidic compound (ii) having a pKa between 1 and 3, and with the proviso that if the inhibitor compound (i) is a substituted benzene that it contains at least two hydroxyl groups bonded directly to the benzene ring.

A method for manufacturing a polylactic acid-based hot melt adhesive includes: (1) preparing a first polylactic acid composition by adding a phosphite and a hindered phenol to a mixture prepared by adding and melt-mixing a first polylactic acid (relative viscosity 2.5-4.0) in a liquid mixture of a dithiocarbamate and a plasticizer at 180 to 280 C., wherein with respect to 100 parts by weight of the first polylactic acid, 10 to 100 parts by weight of the plasticizer, 0.02 to 0.3 parts by weight of the dithiocarbamate, 1 to 10 parts by weight of the phosphite, and 1 to 10 parts by weight of the hindered phenol are used; and (2) mixing a second polylactic acid (relative viscosity 2.5-4.0), into the first polylactic acid composition at 180-280 C., a weight ratio of the first polylactic acid/the second polylactic acid is 2/8 to 8/2.

A polyhydroxypolycarboxylic acid and a water soluble phosphino polycarboxylate may be added to an aqueous system, such as a cooling water system, in order to inhibit corrosion as well as the deposition of corrosion within the system. The water soluble phosphino polycarboxylate may be derived from a phosphinyl unsaturated monomer and an ethylenically unsaturated carboxylic acid monomer. The aqueous system may be a cooling water system such as a cooling tower, a closed cooling water system, an air-conditioning water systems, a wastewater treatment system as well as a deionized water production system.
