| titleOfInvention |
Use of phosphonates as trimerization catalysts for the production of polyisocyanurate synthetic resins |
| abstract |
The instant invention is directed to phosphonates of the formulae: ##STR1## in which n represents an integer of from 0 to 3, n R represents H or --(CH 2 ) m --COOM, n m represents an integer of from 0 to 3, n M represents an alkali metal, or NR' 4 wherein R' represents H or a C 1 -C 4 alkyl group; ##STR2## in which A represents (CH 2 ) x or C 6 -C 10 arylene (preferably phenylene), n x represents an integer of from 0 to 5, n R' and R" which may be the same or different represent n M represents an alkali metal, or NR' 4 . n The invention is also directed to the use of these phosphonates as trimerization catalysts. |
