| abstract |
A moldable and compatible blend of 5 to 95 weight percent of an aromatic polyformal comprising from about 20 weight percent to 100 weight percent of repeating units (I) having the formula <IMAGE> (I) and from 0 weight percent to about 80 weight percent of repeating units (II) having the formula <IMAGE> (II) in which the repeating units (I) and the repeating units (II) are connected by interbonding units (III) having the formula -CH2-(III) wherein Y is selected from alkyl groups of 1 to 4 carbon atoms, chlorine or bromine, each z, independently, has a value of from 0 to 4 inclusive, n has a value of 0 or 1, and R1 is a divalent saturated or unsaturated aliphatic hydrocarbon radical, O, CO, SO2, S or a direct bond, with the proviso that when R1 is SO2 then repeating unit (II) is not the same as repeating unit (I), and 95 to 5 weight percent of a styrene copolymer or terpolymer and/or vinyl chloride containing polymers. |
