12 Jun 1990TL;DR: In this article, a process for the preparation of a polyurethane coating by coating a substrate with a coating composition containing a polyisocyanate component and an isocyanates-reactive component containing at least one compound corresponding to the formula ##STR1## was described.
Abstract: The present invention relates to a process for the preparation of a polyurethane coating by coating a substrate with a coating composition containing a) a polyisocyanate component and b) an isocyanate-reactive component containing at least one compound corresponding to the formula ##STR1## wherein X represents an organic group which has a valency of n and is inert towards isocyanate groups at a temperature of 100° C. or less, R 1 and R 2 may be identical or different and represent organic groups which are inert towards isocyanate groups at a temperature of 100° C. or less, R 3 and R 4 may be identical or different and represent hydrogen or organic groups which are inert towards isocyanate groups at a temperature of 100° C. or less and n represents an integer with a value of at least 2, and curing the coating composition at a temperature of 100° C. or less.

TL;DR: In this paper, a method of protecting a substrate against damage comprising disposing on a substrate one or more coatings, wherein one coating comprises an isocyanate-terminated polyurethane prepolymer and a curing agent, wherein the curing agents comprise polyaspartic esters, ketimines, aldimines or a combination comprising at least one of the foregoing curing agents, is presented.
Abstract: A method of protecting a substrate against damage comprising disposing on a substrate one or more coatings, wherein one coating comprises an isocyanate-terminated polyurethane prepolymer and a curing agent; wherein the curing agents comprise polyaspartic esters, ketimines, aldimines, or a combination comprising at least one of the foregoing curing agents; reacting the isocyanate-terminated polyurethane prepolymer with a curing agent; wherein the reacting can optionally be carried out in the presence of moisture or heat; and curing the isoycyanate-terminated polyurethane prepolymer to form the coating.

30 Jul 2018TL;DR: In this paper, a review compiles the work carried on developing polyaspartic acid based superabsorbent polymers, which are widely used in many applications such as disposable diapers, feminine napkins, soil for agriculture and horticulture.
Abstract: Superabsorbent polymers are widely used in many applications such as disposable diapers, feminine napkins, soil for agriculture and horticulture, gel actuators, water-blocking tapes, drug delivery systems, absorbent pads and other biomedical applications. Most of these superabsorbents are non-biodegradable and thus increasing burden on the earth. Polymer scientist and chemists are looking for environmental friendly solutions. Polyaspartic acid polymers have been reported to possess biodegradable properties. These polymers have been developed mainly as polyelectrolyte. However, this review compiles the work carried on developing polyaspartic acid based superabsorbent polymers. The review covers synthetic methodology, characterization of these polymers by different techniques, different types of polymer prepared using polyaspartic polymers which include co-polymers, grafted polymers, interpenetrating and semi-interpenetrating polymers are covered. The biodegradability studies carried out on the superabsorbent polymers are also discussed.
