Elastomer Agglomerate Production via High-Pressure Homogenization

The patent replaces the chemical polymerisation process with a mechanical pressure agglomeration process. By applying high pressure (typically 10-100 MPa) to the elastomeric particle slurry, the particles are forced together and fuse to form agglomerates with the desired average particle size. This mechanical approach eliminates the need for lengthy polymerisation reactions while achieving the same particle size enlargement goal.

The patent substitutes the chemical agglomeration method with a mechanical pressure-based method. High pressure is applied to the elastomeric particle slurry to induce particle fusion and agglomeration without introducing any chemical reagents. This mechanical approach achieves particle size enlargement while keeping the elastomeric particles free from chemical impurities, ensuring the final core-shell copolymer properties are not compromised.

The patent employs parameter optimization to control the particle size distribution during pressure agglomeration. By carefully adjusting key parameters including pressure magnitude (10-100 MPa), pressure duration, slurry composition, and temperature, the process achieves both high productivity and precise control over the average particle size of the elastomer agglomerates. This parameter-based control allows the fast mechanical process to produce consistent, predictable particle sizes suitable for core-shell copolymer synthesis.
