POLYVINYLKLORIDBASERAD PRESSMASSA

Plate-out in the processing of moulding compositions based on PVC and PVC copolymers can be substantially suppressed if the moulding compositions contain specific silane compounds. These silane compounds are silanes of the formula: CH2 = CH - Si(OR)3 or R' - (CH2)n - Si(OR)3 or R'' -...

Zusammenfassung:	Plate-out in the processing of moulding compositions based on PVC and PVC copolymers can be substantially suppressed if the moulding compositions contain specific silane compounds. These silane compounds are silanes of the formula: CH2 = CH - Si(OR)3 or R' - (CH2)n - Si(OR)3 or R'' - O - (CH2)3 - Si(OR)3 or Cl - (CH2)m - Si(OR)3 in which R' is NH2 and m is 1 or 2 and n is 1, 2 or 3 and R'' is and R is an alkyl radical or an acyl radical having 1 to 18 carbon atoms, and where the alkyl radical may optionally be interrupted a number of times by oxygen, or corresponding silanols or disiloxanes or oligomeric siloxanes thereof.
