DETAILED DESCRIPTION OF THE INVENTION The polymeric composition of the present invention is prepared by thoroughly stirring, in a conventional mixer for viscous liquids (polypropylene glycol)diurethanediepoxide having a molecular weight of 1000 to 2500 and diglycidyl ether of bisphenol A having a molecular weight of 300 to 700 for 30 to 40 min, subsequently adding a curing agent to the mixture, and again stirring it for 15 to 20 min.
The curing agent is prepared by thoroughly stirring m-phenylene-diamine and aniline taken in the weight ratio of 0.
9 to 1:1 within a conventional mixer until m-phenylene-diamine completely dissolves in aniline.
It is possible, by changing mass or molar ratio of (polypropylene glycol)diurethanediepoxide and diglycidyl ether of bisphenol A, while adding a certain amount of said curing agent to the composition, to vary the physico-chemical and mechanical properties of this composition over a wide range.
To prepare the polymeric composition with properties dictated by the application of the composition, a mineral filler is added thereto.
This mineral filler may be zink oxide, or titanium dioxide, or cadmium oxide, or chromium oxide, or iron oxide, or manganese oxide, or manganese dioxide, or alumina, or lead oxide, or kaolin, or talc, or asbestos, or carbon black, or chalk, or graphite, or wood powder, or cement, or zink powder, or aluminium powder and others, or mixtures thereof.
The composition containing a filler is prepared in the following way.
A conventional mixer for viscous liquids is charged with (polypropylene glycol)diurethanediepoxide and a mineral filler.
The latter is charged batchwise under stirring.
Then diglycidyl ether of bisphenol A is added to said mixer.
The mixture thus obtained is stirred until a uniform viscous mass is obtained, and a curing agent is added thereto, whereupon the mixture is again stirred for 15 to 20 min.
The curing agent is prepared as described above.
The polymeric composition of the present invention in an uncured state is a cream-colored liquid having a viscosity of 150 to 450 P
