Abstract 1. A LOW-DENSITY, LUSTROUS ACRYLIC FIBER OF REDUCED SOILING TENDENCIES COMPRISING A FIBER-FORMING FIRST ACRYLONITRILE POLYMER CONTAINING AT LEAST 70 WEIGHT PERCENT ACRYLONITRILE AND THE BALANCE OF ONE OR MORE VINYL MONOMERS AND, AS SMALL DISCONTINUOUS ELONGATED SEGMENTS WITHIN SAID FIRST POLYMER SEPARATED THEREFROM BY VOID SPACE, FROM ABOUT 1 TO 10 WEIGHT PERCENT, BASED ON THE TOTAL WEIGHT OF HE FIBER, OF A SECOND ACRYLONITRILE COPOLYMER INCOMPATIBLE WITH SAID FIRST POLYMER AND CONTAINING FROM 50 TO 95 WEIGHT PERCENT ACRYLONITRILE AND FROM 5 TO 50 WEIGHT PERCENT OF A MONOMER OF THE FORMULA CH2=C(-R1)-COO-R2 WHEREIN R1 IS HYDROGEN OR METHYL AND R2 IS SELECTED FROM HYDROGEN, HYDROXYALKYL OF 2 TO 4 CARBON ATOMS AND (CH2CH20)NR3 WHEREIN N IS AN INTEGER OF ABOUT 1 TO 50 AND R3 IS SELECTED FROM HYDROGEN, ALKYL OF 1 TO 4 CARBON ATOMS, AND ARYL OF MONOCYCLIC STRUCTURE HAVING LESS THAN ABOUT 10 CARBON ATOMS.
A LOW-DENSITY, LUSTROUS ACRYLIC FIBER OF REDUCED SOILING TENDENCIES COMPRISING A FIBER-FORMING FIRST ACRYLONITRILE POLYMER CONTAINING AT LEAST 70 WEIGHT PERCENT ACRYLONITRILE AND THE BALANCE OF ONE OR MORE VINYL MONOMERS AND, AS SMALL DISCONTINUOUS ELONGATED SEGMENTS WITHIN SAID FIRST POLYMER SEPARATED THEREFROM BY VOID SPACE, FROM ABOUT 1 TO 10 WEIGHT PERCENT, BASED ON THE TOTAL WEIGHT OF HE FIBER, OF A SECOND ACRYLONITRILE COPOLYMER INCOMPATIBLE WITH SAID FIRST POLYMER AND CONTAINING FROM 50 TO 95 WEIGHT PERCENT ACRYLONITRILE AND FROM 5 TO 50 WEIGHT PERCENT OF A MONOMER OF THE FORMULA CH2=C(-R1)-COO-R2 WHEREIN R1 IS HYDROGEN OR METHYL AND R2 IS SELECTED FROM HYDROGEN, HYDROXYALKYL OF 2 TO 4 CARBON ATOMS AND (CH2CH20)NR3 WHEREIN N IS AN INTEGER OF ABOUT 1 TO 50 AND R3 IS SELECTED FROM HYDROGEN, ALKYL OF 1 TO 4 CARBON ATOMS, AND ARYL OF MONOCYCLIC STRUCTURE HAVING LESS THAN ABOUT 10 CARBON ATOMS.
