Process for preparing particles of aromatic polymers, particles obtainable by said process and their uses
The invention relates to a process for preparing polymeric particles, based on the use of a polyester polymer (PE) comprising units from a dicarboxylic acid component and a diol component, wherein at least 2 mol. % of the diol component is a poly(alkylene glycol). The process comprises the melt-blending of the aromatic polymer (P) with the PE, the cooling the blend and the recovery of the particles by dissolution of the PE into water. The present invention relates to polymeric particles obtained therefrom and to the use of these particles in SLS 3D printing, coatings and toughening of thermoset resins.
COMPOSTABLE BIOPLASTIC AND METHODS OF MANUFACTURE
A method of manufacturing a biodegradable bioplastic includes preparing a plant derived polymer base, preparing bamboo extracts from bamboo wood, and combining the bamboo extracts with the polymer base, optionally by heating and mixing the polymer base in a liquid form together with the bamboo extracts in a liquid form. The bamboo extracts may be applied as a surface treatment of the polymer base, with the polymer base in a solid form. The plant derived polymer base may include water, potassium bicarbonate, glycerol and starch, such as arrowroot. The plant derived polymer base and the bamboo extracts may be combined at ambient temperature, heated, cooled, reheated and recooled and solidified.
