摘要： THE PRESENT INVENTION IS DIRECTED TO A BLOCKED ISOCTANATE POLYMER OF THE GENERAL FORMULA:

(B(NCO)-A-NH-COO)M-M(-COOH)P(-OH)(N-M)-(COO(-)Z(+))Q, OR

((B(NCO))2-A-NH-COO)M-M(-COOH)P(-OH)(N-M)-(COO(-)Z(+))Q

WHEREIN BNCO IS A BLOCKED NCO GROUP, A IS A RADICAL DERIVED BY REMOVING ALL NCO GROUPS FROM AN ORGANIC DIISOCYANNATE IN COMPOUND I OR AN ORGANIC TRIISOCYANATE IN COMPOUYND II, M IS A RADICAL DERIVED BY REDUCING ALL OH GROUPS AND CARBOXYL AND ITS SALT GROUPS FROM A HIGH MOLECULAR COMPOUND HAVING A MOLECULAR WEIGHT OF ABOUT 350 TO ABOUT 30,000 AND AN ACID VALUE OF ABOUT 30 TO ABOUT 350 AND CONTAINING N OH GROUPS PER MOLECULE AND CARBOXYL GROUPS, ABOUT 40 TO 100 MOLE PERCENT OF WHICH ARE IN THE FORM OF A QUATERNARY AMMONIUM SALT OR ALKALI METAL SALT, N AND M ARE POSITIVE NUMBERS OF NOT LESS THAN 1, WHEREIN (2+N) IN FORMULA I AND (3+N) IN FORMULA 11 ARE BOTH AT LEAST 5, WHEREAS N/2M IN FORMULA 1 AND N/3M IN FORMULA 11 ARE MORE THAN ABOUT 0.5, BUT LESS THAN ABOUT 4.0, Z IS A QUATERNARY AMMONIUM CATION OF ALKALI METAL CATION, (P+Q) IS SUCH A NUMBER THAT A COMPOUND OF (HO)N-M-(COOH)P+Q HAS AN ACID VALUE OF ABOUT 40 TO ABOUT 150, AND Q/(P+Q)X100 IS 100 TO ABOUT 40. THE PRESENT INVENTION, SIMILARLY, RELATES TO A METHOD OF PRODUCING THE AFOREMENTIONED BLOCKEDISOCYANATE POLYMER TYPE COMPOUNDS. THESE COMPOUNDS ARE USEFUL AS COATING AGENTS, ADHESIVE AGENTS AND THE LIKE.

摘要： NOVEL PARTIALLY BLOCKED ISOCYANATE POLYMERS SUITABLE FOR THE PREPARATION OF THREE DIMENSIONAL COATING FILMS ARE PREPARED. THE COATING FILMS ARE PREPARED BY HEATING THE BLOCKED ISOCYANATES IN THE PRESENCE OF AN ACTIVE HYDROGEN CONTAINING COMPOUND.
