Perfluoroalkylalkylmonocarboxylic acid esters
Abstract
Abstract PERFLUOROALKYLALKYLMONOCARBOXYLIC ACID ESTERS ARE PROVIDED WHICH ARE DERIVED FROM ACYCLIC ALIPHATIC EPOXIDES. THESE ESTERS CONTAIN AT LEAST ONE PERFLUOROALKYL RADICAL WITH 4 TO 14 CARBON ATOMS WHICH IS BONDED OVER AN ALKYLENE GROUP WITH 1 TO 10 CARBON ATOMS TO A CARBOXYL GROUP, WHICH IN TURN IS BONDED IN A ESTER-LIKE MANNER TO AN ACYCLIC RADICAL. THIS RADICAL CONTAINS IN THE 2-POSITION TO THE ESTER BRIDGE AN OPTIONALLY ETHERIFIED OR ESTERIFIED HYDROXYL GROUP; SAID RADICAL IS BONDED VIA AN ESTER, ETHER OR CARBAMATE BRIDGE TO AN ALKENYL GROUP WITH 2 TO 3 CARBON ATOMS WHICH IS OPTIONALLY LINKED VIA A SECOND ESTER, ETHER OR CARBAMATE BRIDGE TO AN ACYCLIC RADICAL WHICH IN TURN MAY BE BONDED VIA AN ESTER BRIDGE AND AN AKYLENE GROUP TO A PERFLUOROALKYL RADICAL. THE PERFLUOROALKYLALKYLMONOCARBOXYLIC ACID ESTERS AND ALSO THEIR HOMOPOLYMERS OR THEIR COPOLYMERS WITH OTHER POLYMERISABLE PRODUCTS ARE USED TO ACHIEVE OLEOPHOBIC FURNISHES ON POROUS OR NON-POROUS SUBSTRATES, ESPECIALLY ON FIBROUS MATERIALS, SUCH AS TEXTILES AND PAPERS.
