SHOCK RESISTANT POLY(METH)ACRYLATE MOULDING COMPOUND WITH HIGH HEAT RESISTANCE Russian patent published in 2010 - IPC C08L33/10 C08F265/06 

FIELD: chemistry.

SUBSTANCE: invention relates to polymer mixtures for making shock resistant moulded articles. The disclosed polymer mixture for making moulded articles which contains (meth)acrylate (co)polymer components with different molecular weight and viscosity of solution in chloroform, and an impact viscosity modifier based on cross-linked poly(meth)acrylates, having a nucleus/shell/shell structure, whereby the test sample made from the polymer mixture simultaneously possess the following characteristics: Young's modulus of elasticity (ISO 527) of at least 2500 MPa, Vicat softening point VET (ISO 306-B50) of at least 110°C, impact viscosity (ISO 179-2D, perpendicular the layers) of at least 30 kJ/m², flow melt index MVR (ISO 1133, 230°C/3.8 kg) of at least 1.0 cm³/10 min. The invention also discloses articles injection moulded from the said polymer mixture, use of the polymer mixture to obtain moulded articles and versions of using the obtained moulded articles.

EFFECT: design of thermoplastic material with a balanced profile of characteristics.
