    Abstract: Novel thiol-terminated hydroxyamides, and processes for their preparation and use are provided. These hydroxyamide compounds may be prepared by the reaction of a mercapto-functional alkyl ester, such as methylmercaptopropionate, with a molar excess of an alcohol-substituted amine, such as a .beta.-hydroxyalkyl amine. The thiol-terminated hydroxyamides are useful as polymerization chain transfer agents, particularly when it is desirable to form polymers or oligomers containing functional hydroxyamide end groups. By chain terminating such polymers or oligomers with reactive hydroxyamide end groups the polymers or oligomers can be further reacted with acid-containing monomers or polymers to form block or graft copolymers.

These hydroxyamide compounds may be prepared by the reaction of a mercapto-functional alkyl ester, such as methylmercaptopropionate, with a molar excess of an alcohol-substituted amine, such as a b-hydroxyalkyl amine. The thiol-terminated hydroxyamides are useful as polymerization chain transfer agents, particularly when it is desirable to form polymers or oligomers containing functional hydroxyamide end groups. By chain terminating such polymers or oligomers with reactive hydroxyamide end groups the polymers or oligomers can be further reacted with acid-containing monomers or polymers to form block or graft copolymers.

    Abstract: A process for encapsulating a wide variety of target materials, including both hydrophilic and hydrophobic materials, employs condensation of two reactive compounds to form shells around core phase particles including target material dispersed in a continuous phase. One of the reactive compounds has at least two active methylene functional groups per molecule, the other being an active methylene-reactive crosslinking agent. Either type of the reactive compounds can be dispersed in the continuous phase, the other being dispersible in the core phase. Applications include controlled release microencapsulation of agriculture chemicals and biocides.
