A systematic study of the influence of plastic deformation and low temperature ageing on the carbon Dislocation Enhanced Finkelshtain Rosin Effect (DEFREIC) in austenitic alloys of Fe-Ni, Fe-Ni-MO, Fe-Mn-A1 and Fe-Cr-Ni systems with different carbon content is reported. The experiments prove that after plastic deformation at room temperature the FR effect is transformed into DEFREIC. nith both ...

Graft copolymerization of rosin-(2-acryloyloxy)ethyl ester (RAEE) onto chitosan (Cts) was carried out under microwave irradiation using potassium persulfate as an initiator. The structures, morphology, and thermal properties of the Cts graft copolymer (Cts-g-PRAEE) were characterized by means of FT-IR, XRD, SEM, and TG. Also, Cts and Cts-g-PRAEE copolymer were used as carriers of fenoprofen cal...

The features of the process chemical modification polyaminoamides based on adipic acid and diethylenetriamine with rosin-maleic adducts differing in content maleopimaric (8.55; 16.46 31.12 % wt.) are considered. Modification amount equal to number secondary amino groups repeating unit polymer was carried out melt at temperature 160–180 °C for 3 h under continuous stirring. controlled by monitor...
