A sulfonic acid salt of an acyloxyalkylamine is prepared by reaction of an organic acid or amino-acid with a sulfonic acid salt of an alkanolamine. Isocyanates are prepared therefrom by reaction with phosgene.

Method of preparing sulfonic acid salts of acyloxyalkylamines and

Polymers of esters of methacrylic acid having an average chain length of about 6 to about 50 mers are prepared by an anionic polymerization reaction, carried out in the presence of a chain-regulating alcohol and a catalytic amount of an alkoxide anion, in which control of the molecular weight and molecular weight distribution of the polymer are achieved by regulating the ratio of the total quantity of alcohol employed to the total monomer charge. These polymers, their hydrolysis products, and their derivatives have a wide variety of applications, including use as components in films, coatings, fibers, impregnants, adhesives, printing inks, and binders, and use as modifiers, plasticizers, melt flow improvers, and leveling agents.

Novel polymers of alkyl methacrylates

Polymers of esters of acrylic acid having an average chain length of about 6 to about 30 mers are prepared by an anionic polymerization reaction, carried out in the presence of a catalytic amount of an alkoxide anion. These polymers, their hydrolysis products, and their derivatives have a wide variety of applications, including among others use as components in films, coatings, fibers, impregnants, adhesives, and binders, and use as modifiers, plasticizers, melt flow improvers, and leveling agents.

Novel polymers of alkyl acrylates

Polymers of esters of methacrylic acid having an average chain length of about 6 to about 50 mers are prepared by an anionic polymerization reaction, carried out in the presence of a chain-regulating alcohol and a catalytic amount of an alkoxide anion, in which control of the molecular weight and molecular weight distribution of the polymer are achieved by regulating the ratio of the total quantity of alcohol employed to the total monomer charge. These polymers, their hydrolysis products, and their derivatives having condensation-crosslinkable functionality have a wide variety of applications, including use as components in films, coatings, fibers, impregnants, adhesives, printing inks, and binders, and use as modifiers, plasticizers, melt flow improvers, and leveling agents.

Novel methacrylic polymers having condensation-crosslinkable

Polymers of esters of methacrylic acid having an average chain length of about 6 to about 50 mers are prepared by an anionic polymerization reaction, carried out in the presence of a chain-regulating alcohol and a catalytic amount of an alkoxide anion, in which control of the molecular weight and molecular weight distribution of the polymer are achieved by regulating the ratio of the total quantity of alcohol employed to the total monomer charge. These polymers, their hydrolysis products, or their hydroxyl-containing derivatives are esterified or transesterified to give polymers having pendant acrylate or methacrylate functionality which are useful in formulating films, coatings, inks, and the like.
