| titleOfInvention | Block copolyetheramides flexible at low temperatures |
| abstract | Homogeneous, flexible block copolyetheramides having a melting/softening point of at least 170° C., a glass transition temperature, measured at ZHE, of at most -5° C., and a melt viscosity of at least 500 poises, said block copolyetheramides comprising the oxyacid, or alkali or alkaline earth metal, such oxyacid salt catalyzed polycondensate of admixture of (i) a lactam having from 4 to 12 carbon atoms with (ii) a solution of (iii) a salt of a fatty acid dimer and a polyoxyalkylenediamine, or mixture thereof, with a triamine, in (iv) a solvent medium which comprises (1) a mixture of water and an aliphatic alcohol having less than 5 carbon atoms, (2) a water/alcohol/lactam mixture wherein the alcohol and lactam are as in (1), (3) a melt of said lactam, or (4) a mixture of water and a water-soluble such lactam, the stoichiometry of said salt (iii) having been carefully pre-adjusted such that the pH thereof is essentially that as exists at the equivalence point thereof, and said oxyacid comprising at least one acid function having a pKa of no greater than 4. |
