Abstract A method of surface modification of polymer materials, according to which said materials are treated with an aqueous solution comprising a mineral acid, a mineral oxidant, and a salt of hydrochloric, hydrobromic, or hydroiodic acid. Water, said mineral acid, mineral oxidant and salt are taken in a weight ratio of 50-1000:0.3-7:0.1-7:1-15 respectively. By carrying out modification of polymer materials in accordance with the present method, the initial strength of the treated materials remains unaffected. Moreover, in the process of treating the materials, the latter acquire desired adhesion properties, whereby strength of cementing of polymer materials with each other, with metals, wood, glass-reinforced plastics and glass is ensured.
A METHOD OF SURFACE MODIFICATION OF A POLYMER SELECTED FROM THE GROUP CONSISTING OF ISOPRENE RUBBER, STYRENEBUTADIENE RUBBER, AND NATURAL RUBBER, TO THEREBY IMPROVE SUBSTANTIALLY THE SURFACE ADHESION PROPERTIES THEREOF, COMPRISING TREATING SAID POLYMER WITH AN AQUEOUS SOLUTION COMPRISING A MINERAL ACID, A MINERAL OXIDANT SELECTED FROM THE GROUP CONSISTING OF POTASSIUM BROMATE, POTASSIUM PERMANGANATE, AND SODIUM PERCHLORATE AND A MEMBER OF THE GROUP CONSISTING OF SODIUM, POTASSIUM, AND ZINC SALTS OF HYDROCHLORIC, HYDROIODIC AND HYDROBROMIC ACIDS, THE WATER, SAID MINERAL ACID, SAID MINERAL OXIDANT AND SAID SALT IN SAID AQUEOUS SOLUTION BEING TAKEN IN A WEIGHT RATIO OG 50-1000:0.3-7:1:15, RESPECTIVELY.
