Provided is a resin composition used for forming a laminated glass interlayer film or a solar cell encapsulant, the resin composition including an ionomer (A) of an ethylene-unsaturated carboxylic acid-based copolymer, wherein metal ions constituting the ionomer (A) of the ethylene-unsaturated carboxylic acid-based copolymer includes two or more kinds of polyvalent metal ions.

The present invention relates to a process for preparing a vulcanisable elastomeric compound for tyres, characterised by the use of a particular vulcanisation-activating filler and by the methods of adding additives, in particular the compatibilising agent (silane), which occurs only after completion of the reaction between the activating filler comprising zinc and the fatty acid (stearic acid). The present process, advantageous in itself due to the possible reduction of the times and of the energy required for vulcanisation, allows preparing compounds which, with the same performances compared to the traditional ones, can have a reduced zinc content, and consequently a lower release thereof from tyres during use at an environmental level.

Methods of protecting a surface include applying an inner polymer layer onto a surface. The inner polymer layer is impregnated with a biologically active chemical substance that protects the surface from biofouling-induced chemical, biological, and bio-proliferative damage.
