Antistatic agents, synthesis and use thereof

Claim 2

A process for the manufacture of an antistatic agent useful for the manufacture of an antistatic polyester fiber which comprises: (i) reacting about one mole of a dimetallic compound selected from the group consisting of compounds of Be, Mg, Ca, Sr, Ba, Zn and Cd and about two moles of same or different acyl compounds having the structural formula of: ##STR11## wherein (1) X's, which may be either identical or different, are selected from the group consisting of (a) HO--, (b) NH 2 --, (c) OHSO 3 --and (d) Cl--, Br--, or I--; (2) R is selected from the group consisting of (a)--(CH 2 ) n --, wherein n is an integer ranging from 1 to 8, (b)--(HC═CH) k --, wherein k is either 1 or 2, (c)--(C.tbd.C)--, ##STR12## (ii) reacting the product formed in step (i) above with a polyalkylene glycol having the structural formula of ##STR13## where p is a number ranging from about 10 to about 1,500 and m is either 2 or 3.

Claim 3

A process for the manufacture of an antistatic polyester fiber which comprises: (a) preparing a master chip polyester by reacting an antistatic agent having the structural formula of: ##STR14## wherein (1) X is selected from the group consisting of (a) HO--, (b) NH 2 --, (c) OHSO 3 --, and (c) Cl--, Br--, or I--; (2) X 1 's, which can be either identical or different, are selected from the group consisting of (a)--O--, (b)--NH--, and (c)--SO 3 --; (3) R's, which can be either identical or different, are selected from the group consisting of (a)--(CH 2 ) n -- where n is an integer ranging from 1 to 8, (b)--(HC═CH) k where k is either 1 or 2, (c)--(C═C)--, ##STR15## (4) R 1 is a polyalkylene glycol radical having the structural representation of ##STR16## where p is a number ranging from about 10 to about 1,500 and m is either 2 or 3; and (5) M is a divalent metal selected from the group consisting of Be, Mg, Ca, Sr, Ba, Zn and Cd with a common polyester; and thereafter, (b) blending said master chip polyester defined in step (a) above with a common polyester, therby to produce said antistatic polyester fiber.

Claim 4

A process for the manufacture of an antistatic polyester fiber which comprises: (a) preparing a master chip polyester by reacting an antistatic agent having the structural formula of: ##STR14## wherein (1) X is selected from the group consisting of (a) HO--, (b) NH 2 --, (c) OHSO 3 --, and (c) Cl--, Br--, or I--; (2) X 1 's, which can be either identical or different, are selected from the group consisting of (a)--O--, (b)--NH--, and (c)--SO 3 --; (3) R's, which can be either identical or different, are selected from the group consisting of (a)--(CH 2 ) n -- where n is an integer ranging from 1 to 8, (b)--(HC═CH) k where k is either 1 or 2, (c)--(C═C)--, ##STR15## (4) R 1 is a polyalkylene glycol radical having the structural representation of ##STR16## where p is a number ranging from about 10 to about 1,500 and m is either 2 or 3; and (5) M is a divalent metal selected from the group consisting of Be, Mg, Ca, Sr, Ba, Zn and Cd with a common polyester; and thereafter, (b) blending said master chip polyester defined in step (a) above with a common polyester, therby to produce said antistatic polyester fiber.
