| abstract |
NEW EPOXIDE RESIN MIXTURE WHICH CONTAIN A MAJOR PROPORTION OF HIGHER MOLECULAR WEIGHT N,N''-DIGLYCIDYL COMPOUNDS OF OXALKYLATED CYCLIC UREIDE DERIVATIVES ARE OBTAINED BY REACTING 1 MOLE OF AN OXYLATED ACYCLIC UREIDE, SUCH AS 3 - (2'' - HYDROXY - N - PROPYL)-5,5-DIMETHYL HYDANTION, WITH 1.2 TO 3.0 MOLES OF EPIHALOGENOHYDRIN IS KNOWN MANNER. THE NEW EXPOXIDE RESIN MIXTURES ARE SUITABLE FOR THE MANUFACTURE OF MOULDED ARTICLES AND COATINGS WITH GOOD MECHANICAL PROPERTIES AND, IN COMPARISON WITH THE LOW MOLECULAR N,N''-DIGLYCIDYL COMPOUNDS OF OXALKYLATED CYCLIC UREIDES, POSSESS THE ADVANTAGE THAT A SLIGHTER EXOTHERMICITY OCCURS ON GELLING AND A SLIGHTER SHRINKAGE DURING CURING. |
