One part castable liquid thiol-terminated polymer and method of cure

Claim 1

PROCESS FOR CURING A POLYMER IN PLACE COMPRISING: (1) PREMIXING: (A) A SULFONE ACTIVATED DI-ETHYLENIC COMPOUND; (B) A BRANCH CHAIN LIQUID POLYMER TERMINATED WITH THIOL GROUPS AND BEING POLY-FUNCTIONAL WITH RESPECT TO THE THIOL GROUP, THE FUNCTIONALLY BEING GREATER THAN TWO AND LESS THAN SIX, THE BODY OF SAID LIQUID POLYMER BEING COMPOSED OF REPEATING UNITS SELECTED FROM THE CLASS CONSISTING OF ALKYLENE GROUPS OF 1 TO 10 CARBONS, ARYLENE GROUPS OF 1 TO 10 CARBONS, ALKYLENE GROUPS OF 1 TO 10 CARBONS SUBSTITUTED WITH HALOGEN AND ARYLENE GROUPS OF 1 TO 10 CARBONS SUBSTITUTED WITH HALOGEN, SAID GROUPS BEING SEPARATED BY CONNECTING LINKAGES SELECTED FROM THE CLASS CONSISTING OF ESTER, MONOSULFIDE, POLYSULFIDE, URETHANE AND OXIDE; SAID DI-ETHYLENIC COMPOUND AND SAID POLYMER BEING PRESENT IN A RATIO RANGING FROM 0.85 TO 1.15 EQUIVALENT OF DI-ETHYLENIC COMPOUND TO 1 EQUIVALENT OF POLYMER; (C) AN ACID WHICH SUBSTANTIALLY INHIBITS THE CURING OF SAID POLYMER BY SAID DI-ETHYLENIC COMPOUND AND WHICH IS SELECTED FROM THE CLASS OF ORGANIC ACIDS AND ANHYDRIDES CONSISTING OF ALIPHATIC (220 CARBONS), CYCLIC-ALIPHATIC (4-12 CARBONS), AROMATIC (8-12 CARBONS), AND ALIPHATIC-AROMATIC (7-16 CARBONS); (D) A MOLECULAR SIEVE LOADED WITH A NEUTRALIZING BASE WHICH IS CAPABLE OF NEUTRALIZING SAID ACID THEREBY TO ENABLE SAID CURING TO PROCEED; SAID BASE BEING A TERTIARY AMINE SELECTED FROM THE GROUP CONSISTING OF: TRIALKYL AMINES WHERE THE REPEATING UNIT HAS FROM 1 TO 8 CARBONS; MIXED ALKYL ARYL AMINES WHERE THE REPEATING UNIT HAS 1 TO 8 CARBONS; ALIPHATIC-CYCLIC AMINES OF 4-10 CARBONS, AND HETEROCYCLIC AMINES AND DIAMINES OF 4-10 CARBONS; SAID SIEVE HAVING AN EFFECTIVE PORE DIAMETER AT LEAST AS LARGE AS THE EFFECTIVE MOLECULAR DIAMETER OF SAID BASE; (2) EXPELLING SAID BASE FROM SAID SIEVE AND INTO NEUTRALIZING REACTION WITH SAID ACID; AND (3) REACTING SAID DI-ETHYLENIC COMPOUND WITH SAID POLYMER BY VIRTUE OF THE NEUTRALIZING OF THE INHIBITING ACTION OF SAID ACID, THEREBY EFFECTING SAID CURING OF SAID POLYMER BY SAID DI-ETHYLENIC COMPOUND.
