摘要:
The invention relates to 5-oxo-3-pyrrolidinecarboxylic acid derivatives having the structural formula ##STR1## wherein X is selected from the group of ##STR2## R.sub.2 and R.sub.3 are each H or CH.sub.3, and R.sub.1 is H or a hydrocarbon radical having from 1 to 20 carbon atoms, which derivative compounds are suitable as monomers which can be homopolymerized or copolymerized to yield high molecular weight materials having many useful properties and applications, among which is their ability to form complexes with water insoluble molecules which are normally not complexible with similar type polymers.
摘要:
What is described herein are polymerizable pyrrolidonyl 4,5-unsubstituted oxazoline monomers, homopolymers thereof, and copolymers with other monomers. A preferred polymerizable monomer compound is 2-(1-methyl-2-pyrrolidon-4-yl)-2-oxazoline. The polymers herein have excellent hydrotropic properties thus increasing the water solubility of organic compounds previously considered as water insoluble, and exhibit complexation with water soluble cosolutes.
摘要:
What is provided herein is a method for preparing discrete microdroplets of a high viscosity oil in water stabilized by in situ polymerization of a water-soluble vinyl monomer. The method comprises dispersing the oil in water containing a surfactant, adding the water-soluble vinyl monomer, preferably vinylpyrrolidone, optionally with a comonomer, and polymerizing the monomer or comonomers in situ such that the oil is stabilized in the resulting polymer solution as discete microdroplets.

摘要:
The present invention relates to latex compositions comprising hydroxyethyl cellulose grafted acrylic polymer emulsions and methods for preparing same without gelling or coagulation. The latex composition comprises at least about 0.2% of HEC by weight relative to the monomer weight, contains at least about 45% solid, and the average mean volume (mV) latex particle size is in the range of about 320-about 850 nm. Paint compositions incorporating the HEC grafted acrylic latex show high viscosity at static conditions and have no color flow and no syneresis compared paints containing a latex without HEC grafting. The present invention also relates to a cross-linking mechanism that cross-links latex particles at ambient conditions. This cross-linking mechanism comprises diacetone acrylamide (DAAM) and methacrylamide (MAM) with or without styrene.
