  • Aminopolyols and polyurethanes prepared therefrom
    Patent number: 4696771
    Abstract: Novel aminopolyols are the products of the reaction of an N-substituted ethanolamine with a terminal epoxy-containing compound. The epoxy-containing compounds may be:I. terminal mono-epoxy-containing aliphatic hydrocarbons,II. mono-glycidyl ethers of aliphatic hydrocarbons,III. mono-glycidyl esters of fatty acids, andIV. di-glycidyl ethers of bisphenols.The novel aminopolyols are useful in the preparation of novel polyurethanes by reaction with polyisocyanates.

  • N-Alkyl polyamines and curing of epoxy resins therewith
    Patent number: 4195152
    Abstract: There is disclosed a class of N-alkylpolyamines and their use as curing agents for epoxy resins, and in particular to such polyamines having the formula R--[NH(CH.sub.2).sub.x ].sub.y --NHR' where R is an aliphatic hydrocarbon radical having from 5 through 8 carbon atoms, R' is H, R or R", x is an integer of 2 or 3 and y is an integer of 2-4. A monoepoxide adduct of the monoalkyl substituted polyamine is also disclosed wherein R" may then become an aliphatic substituent (2-14 carbon atoms) which may contain (a) an oxygen atom, (b) a hydroxyl group or (c) an aromatic substituent such as a phenyl ring.

  • Aminopolyamide-acrylamide-glyoxal resin
    Patent number: 4060507
    Abstract: Disclosed are novel aminopolyamide-acrylamide-glyoxal resins useful as a sizing agent for paper having low water absorption, a desirable property for sized paper. The products are water dispersible and/or soluble and also find utility in printing inks, textile treatment and cosmetic or beauty aid compositions. The aminopolyamide is the condensation product of a polymeric fat acid and polyalkylene polyamine.
