摘要： In one aspect, methods of depolymerization are described herein comprising providing a synthetic polymer including a hydroxylated aliphatic backbone or hydroxylated backbone segments, and homolytically activing O—H bonds of the hydroxyl groups. Homolytic activation induces the formation of alkoxy radical intermediates followed by C—C bond β-scission events breaking the polymer backbone into depolymerization products. In some embodiments, depolymerization products comprise alkyl radical intermediates reduced by hydrogen atom transfer. Moreover, in some embodiments, the depolymerization products are further reacted into difunctionalized products or comprise functionalities derived from the polymer structure. The difunctionalized products can subsequently be employed in polymerization processes for the production of additional synthetic polymers.

摘要： A method for manufacturing a fibre reinforced composite by means of a vacuum assisted resin transfer moulding, comprising the steps of placing a fibre material in a mould, placing a flow distribution medium onto the fibre material, and covering the fibre material (1) and the flow distribution medium with a vacuum foil for forming a closed mould cavity between the mould and the vacuum foil is described. It is characterised in using a flow distribution medium with a thickness depending on a pressure gradient over the vacuum foil.
