| abstract |
Non-cellulosic, synthetic polymeric materials are made bondable to themselves and to other materials, without the use of external binders or temperatures at the melting point of the polymer, by treating the surface with certain chemicals such that after the removal of these chemicals, a water-induced bonding of these materials can be effected. The specific polymers include the polyolefins, polyamides, polyesters and polyacrylics. The preferred treatment is one involving sulphating/sulfonation and oxidation. |
