Abstract
Covers a new composition of matter comprising an acrylamide or methacrylamide monomer characterized by the following structural formula: ##STR1## where R.sub.1, R.sub.2 and R.sub.5 are hydrogen or methyl, R.sub.3 and R.sub.4 are lower alkyl, n is an integer ranging from 1 to 6 and A represents an anion.
Claims5
An acrylamide or methacrylamide quaternary characterized by the following structural formula:
- ##STR8## where R.sub.1, R.sub.2 and R.sub.5 are hydrogen or methyl, R.sub.3 and R.sub.4 are lower alkyl, n is an integer ranging from 1 to 6 and A represents an anion.
In a process for preparing a polymer containing recurring isocyanurate and urethane linkages, which polymer comprises the reaction product of a polyether or polyester polyol and an aromatic polyisocyanate, while utilizing an isocyanurate group formation catalyst;
- the improvement which comprises employing as said isocyanurate catalyst an acrylamide or methacrylamide quaternary which comprises a compound falling within the following structural formula:
- ##STR9## where R.sub.1, R.sub.2 and R.sub.5 are hydrogen or methyl, R.sub.3 and R.sub.4 are lower alkyl, n is an integer ranging from 1 to 6 and A represents an anion.
