An extensive analysis of the possibilities and goal in the application of composites as an alternative to thermoplastic polymer composites filled with minerals has been presented. The analysis was made taking into special consideration the mechanical properties and applicability of polypropylene composites, which are widely used and well characterized. It was shown that the enthusiasm and expectations linked with the vision of the application of thermoplastics filled with plant fibers from widely available renewable sources as cheap materials with attractive properties has not been fully justified. The realistic solution would be maintaining the production of these new materials derived from waste polyolefins and renewable fiber materials from agriculture and forestry industries for low-end applications.

A method for the synthesis of polystyrene of reduced flammability by suspension polymerization in the presence of organic phosphor compounds or their compositions with organically modified layered aluminosilicates of the montmorillonite type has been developed. The additives or their compositionswere introduced into the polystyrene during suspension polymerization by applying such procedures as to minimize their effects on the process. Polystyrenes of reduced flammability up to maximal vertical and horizontal burning rate categories of V-1 and FH-1, respectively, and of an oxygen index in the 21-26 % range were obtained.

Maleate-doped high d. polyethylene and ethylene/n-octene copolymer were prepd., blended by extrusion with high d. polyethylene and processed to thin wall products with functional channels studied for their structure as well as mech. and thermal properties. The addn. of modifiers resulted in increasing the tensile, flexural and impact strengths. A small decrease in the melting temp, and small increase in the cryst. temp, were also obsd.

According to the Article 2(9) of Regulation (EC) No 1907/2006 of The European Parliament and of The Council of 18 December 2006 concerning the Registration, Evaluation, Authorisation and Restriction of Chemicals (REACH), polymers are exempt from registration and evaluation requirement. However, in accordance with the preamble of REACH Regulation "Polymers should be exempted from registration and evaluation until those that need to be registered due to the risks posed to human health or the environment can be selected in a practicable and cost-efficient way on the basis of sound technical and valid scientific criteria". The article discuss in brief the results of analysis performed for The European Commission, which were presented in The Final Report. It aims to point out, how the registration process of polymers or some types of polymers could appear soon in EU and what producers, importers and downstream users of polymer could expect.

In this project proposal, industry wide harmonized test procedures for PEFC stacks shall be developed and validated. The proposal builds on experiences gained in the FCTESTNET, FCSTEQA series of projects taking up the methodology developed there and expanding it to the test of PEFC stacks. Furthermore, experiences of individual consortium members have long time experience in international standardization. Performance / functional, durability and safety outputs for vehicle propulsion, stationary and portable applications shall be addressed. Generic test modules addressing the effects of outputs to the variation of a single test parameter shall be defined and experimentally validated on a stack level. From these building blocks, selected application oriented test programs shall be derived and validated as well. A two phase approach is pursued starting with an initial selection and definition phase followed by experimental validation. Subsequently, a review is carried out followed by a second validation phase. The consortium mainly consists of experienced research organizations, all working in close contact with and providing testing services to industry. The test modules and test programs are expected to be methodologically sound and independent. Contact to industrial practice will be established by the implementation of an industrial advisory group consisting of selected key stakeholders along the value chain of the fuel cell industry. The consortium will liaise with international standardization activities and contribute to the improvement of existing standards by pre-normative research and if deemed necessary initiate new work item proposals on performance and endurance testing of PEFC stacks.

The present invention relates to the method for separating toluene diisocyanate from the post-reaction mixture in the toluene diamine phosgenation process in the gas phase. More specifically the solution concerns obtaining a higher TDI concentration in the liquid reaction product. The method is based on the fact that cooling and condensation of the reaction product - toluene diisocyanate - (TDI) is carried out by the application of spraying in the cooling and condensation zone, directly after the reactor, wherein this operation is carried out at a temperature elevated enough to obtain a low concentration of the solvent, i.e. within 5-30% by weight, in relation to TDI obtained, and thus a high concentration of (within 70-95% by weight) TDI obtained.
