Abstract: THE DISCLOSURE IS DIRECTED TO MODIFIED CROSS-LINKED STARCH PRODUCTS IN THE GRANULAR FORM. PASTES OF THESE STARCH PRODUCTS HAVE SUBSTANTIALLY STABLE VISCOSITIES AT ELEVATED TEMPERATURES AND DRY FILMS OF THE PRODUCTS ARE MORE SOLUBLE THAN FILMS PREPARED FROM UNTREATED STARCH. ALSO, PASTES OF THE MODIFIED CROSS-LINKED STARCH PRODUCTS ARE SUBSTANTIALLY-RETROGRADABLE. THE MODIFIED CROSS-LINKED STARCH PRODUCT IS A PARTIALLY DEPOLYMERIZED FORMALDEHYDE CROSS-LINKED STARCH PRODUCT HAVING A 60-MINUTE BRABENDER VISCOSITY OF FROM ABOUT 70 TO ABOUT 125 PERCENT OF THE PEAK VISCOSITY AND A GEL STRENGTH OF LESS THAN 140 GM.-CM. SAID PRODUCT IS PREPARED BY TREATING STARCH GRANULES WITH FORMALDEHYDE AND PARTIALLY DEPOLYMERIZING THE CROSS-LINKED STARCH GRANULES.

Abstract: A gelatinizable crosslinked cationic starch especially suitable for paper sizing is produced by (1) reacting starch with an alkali-catalyzable crosslinking agent and the reaction product of the crosslinking agent with ammonia or with an amine and (2) depolymerizing the resulting cationic crosslinked product.

Abstract: GRANULAR CYANOETHYL STARCHES HAVING BELOW ABOUT 0.06 CYANOETHYL GROUPS PER ANHYDROGLUCOSE UNIT ARE READILY GELATINIZABLE IN WATER AT A NEUTRAL PH, SHOW LESS SLUDGE FORMATION ON STORAGE THAN AQUEOUS PASTES OF UNTREATED STARCH, HAVE LESS TENDENCY TO RETROGRADE WHEN PASTED IN WATER, AND ARE MORE READILY LIQUEFIED BY ALPHA-AMYLASE THAN UNTREATED STARCH.
