    摘要: A welding head for heated tool welding, particularly of thermoplastic materials. The welding head permits independent heating of the welding point on a body and the welding point on a welding part. The welding head has a gripper for receiving the welding part to be welded to the body. It also has a first welding mirror for heating the welding point on the body. A second welding mirror is used for heating the welding point on the welding part. The first welding mirror and the gripper are placed on a common supporting member, which is displaceable by drive means so that alternately the first welding mirror and the gripper are oriented towards the welding point on the body.

C. in a kneader by a method in which the polymerization is carried out to such an extent that the initially formed water-containing polymer gel disintegrates into fine particles and the finely divided polymer obtainable in this manner is hydrolyzed, preferably in the kneader, so that not less than 0.1 mol % of the N-vinylformamide units present in the polymer are converted into vinylamine units. The polymers obtainable in this manner dissolve readily in water. The aqueous solutions are used, for example, in papermaking and tertiary oil production.
