Title:
METHOD FOR PRODUCING IMPACT RESISTANT PLASTICS
Document Type and Number:
WIPO Patent Application WO2001055234
Kind Code:
A3
Abstract:
The invention relates to a method for producing impact resistant plastics on the basis of grafted cross-linked rubber particles. The invention further relates to an impact resistant plastic that is obtained using the inventive method. The method for producing the impact resistant plastic comprises the following steps: (a) producing particles of a cross-linked rubber from a first monomer mixture that has a diene composition content of < 50 wt.%, preferably < 5 wt.-%, especially < 2 wt.-%. The particles of the cross-linked rubber are (b) grafted with a second monomer or monomer mixture and a graft envelope is obtained. The particles of the grafted cross-linked rubber are (c) added to a third monomer mixture and the monomers of the third monomer mixture are (d) polymerized while producing a matrix. The inventive method is simple to carry out and allows for the production of impact resistant plastics with excellent mechanical properties, especially with an improved weathering resistance.
