    Abstract: A process is described for making highly crosslinked polyvinylpyrrolidone (PVP) polymer by popcorn polymerization having a swell volume of less than about 65 ml/10 g, preferably 40-65 ml/10 g, in the absence of added crosslinking agent, and with substantially no induction period. The process comprises (a) providing a reaction mixture of vinylpyrrolidone (VP) monomer at a concentration of about 75-85 % in an aqueous basic solution, containing about 0.4-0.8 % base, under agitation, in an inert gas atmosphere, and at an initial gas pressure of at least 2 bars, (b) heating said mixture at a predetermined temperature and time sufficient to generate an active crosslinker in situ, and (c) reducing the temperature of the mixture to a temperature whereupon popcorn polymerization of said VP monomer commences substantially immediately to form the desired crosslinked PVP.

    Abstract: Described herein are hemi-aminal ethers and thioethers of N -alkenyl cyclic compounds that may be produced through a reaction comprising: (A) at least one first reactant represented by a structure (I), wherein X is a functionalized or unfunctionalized C 1 -C 5 alkylene group optionally having one or more heteroatoms, and each R 1 , R 2 , and R 3 is independently selected from the group consisting of hydrogen and functionalized and unfunctionalized alkyl groups optionally having one or more heteroatoms, and (B) at least one second reactant having at least one hydroxyl moiety or thiol moiety. The hemi-aminal ethers and thioethers of N -alkenyl cyclic compounds may comprise a polymerizable moiety, in which case they may be left as-is or used to create homopolymers or non-homopolymers, or they may not comprise a polymerizable moiety. A wide variety of formulations may be created using the hemi-aminal ethers and thioethers of N -alkenyl cyclic compounds, including personal care, oilfield, and construction formulations.
