THERE ARE DISCLOSED URETHANE ACRYLATES OF FORMULA (1) : WHERE R�?, R�?AND R�? EACH INDEPENDENTLY REPRESENT C???? HYDROCARBYLENE, PREFERABLY LINEAR C???? ALKYLENE (SUCH AS , C??? ALKYLENE; E.G. HEXYLENE); A ISOPHORONE UNIT AND/OR A TOLYL UNIT. R�?, R�? AND R�? EACH INDEPENDENTLY REPRESENT: A DIVALENT MOIETY OF FORMULA (2) WHERE X AND Y INDEPENDENTLY REPRESENT C???? HYDROCARBYLENE, PREFERABLY C??? ALKYLENE; AND K IS FROM O TO 30; I IS FROM O TO 30; AND 'K + I' IS FROM 1 TO 30; AND/OR A DIVALENT MOIETY OF FORMULA (3) WHERE V AND W INDEPENDENTLY REPRESENT C???? HYDROCARBYLENE, PREFERABLY C??? ALKYLENE; AND i IS FROM 0 TO 30; j IS FROM 0 TO 30; AND 'i + j' IS FROM 1 TO 30; P IS FROM 1 TO 10; AND R IS FROM 1 TO 10; AND R�? R� ?AND R�? EACH INDEPENDENTLY REPRESENT H OR METHYL (I.E. R� FORMS RESPECTIVELY PART OF AN ACRYLATE OR A METHACRYLATE GROUP); WITH THE PROVISOS THAT AT LEAST ONE OF R�?, R�?AND R�? IS A MOIETY OF FORMULA (2); AT LEAST ONE OF R�?, R�?AND R�? IS A MOIETY OF FORMULA (3); AND WHEN R2 REPRESENTS A DIVALENT MOIETY OF FORMULA (3), THE SUB MOIETY WITHIN FORMULA (3), IS ATTACHED DIRECTLY TO THE AMIDE GROUP IN FORMULA (1). THE UAs OF FORMULA (1) ARE OF NON CRYSTALLINE AND OF LOW VISCOSITY AND ARE SUITABLE FOR PREPARING POLYMERIC FLEXIBILIZERS SUITABLE FOR TENTING APPLICATIONS. A PROCESS FOR PREPARING THESE URETHANE ACRYLATE IS ALSO DESCRIBED. |
