Title: METHOD FOR REDUCING COLD STRESS WHITENING
Abstract:
The invention relates to a method for reducing undesired coloration changes (Cold Stress Whitening) in impact-resistant thermoplastic moulding compounds (F), caused by low temperatures. Said moulding compounds contain at least one elastomeric graft polymer (A) and at least one thermoplastic polymer (B). According to the invention, 10 to 200 ppm of at least one polyorganosiloxane (S), based upon the moulding compounds (F) is added to said impact-resistant thermoplastic moulding materials (F).
