Abstract

This invention relates to a mixture of a polydiorganosiloxane polyamide-containing material and an organic polymer.

First claim

We claim:

1. A composition comprising:
a bodycare composition; and
an additive, wherein the additive comprises a mixture comprising:
at least one copolymer comprising at least two repeat units of Formula I-b:

wherein:
each R 1 is independently an alkyl, haloalkyl, aralkyl, alkenyl, aryl, or aryl substituted with an alkyl, alkoxy, or halo;
each Y is independently an alkylene, aralkylene, or a combination thereof;
G is a divalent residue equal to a diamine of formula R 3 HN-G-NHR 3 minus the
two NHR 3 groups, wherein G is an alkylene, heteroalkylene, arylene, aralkylene,
or a combination thereof;
R 3 is hydrogen or alkyl or R 3 taken together with G and to the nitrogen to which they are both attached form a heterocyclic group;
n is independently an integer of 0 to 1500; and
p is an integer of 1 to 10; and
at least one thermoplastic organic polymer.

2. The composition of claim 1 , wherein each R 1 of the copolymer is methyl.

3. The composition of claim 1 , wherein each Y of the copolymer is an alkylene having 1 to 10 carbon atoms, phenylene bonded to an alkylene having 1 to 10 carbon atoms, or phenylene bonded to a first alkylene having 1 to 10 carbon atoms and to a second alkylene having 1 to 10 carbon atoms.

4. The composition of claim 1 , wherein the copolymer has a first repeat unit where p is equal to 1 and a second repeat unit where p is at least 2.

5. The composition of claim 1 , wherein n of the copolymer is at least 40.

6. A medical article comprising:
a mixture comprising:
at least one copolymer comprising at least two repeat units of Formula I-b:

wherein:
each R 1 is independently an alkyl, haloalkyl, aralkyl, alkenyl, aryl, or aryl substituted with an alkyl, alkoxy, or halo;
each Y is independently an alkylene, aralkylene, or a combination thereof;
G is a divalent residue equal to a diamine of formula R 3 HN-G-NHR 3 minus the
two NHR 3 groups, wherein G is an alkylene, heteroalkylene, arylene, aralkylene,
or a combination thereof;
R 3 is hydrogen or alkyl or R 3 taken together with G and to the nitrogen to which they are both attached form a heterocyclic group;
n is independently an integer of 0 to 1500; and
p is an integer of 1 to 10; and
at least one organic polymer selected from the group of a hot melt processable

thermoplastic, a hot melt processable elastomeric thermoset, a silicone polymer,
and mixtures thereof; wherein the at least one organic polymer is not a copolymer
comprising at least two repeat units of Formula I-b, is not a tackifying resin, and
is not nylon in the form of fibers.

7. The medical article of claim 6 , wherein the medical article is a contact lens.

8. The medical article of claim 6 , wherein the medical article is a medical tape.

9. The medical article of claim 6 , wherein the medical article is a drug delivery device.

10. The medical article of claim 6 , wherein the medical article is a medical backing.

11. A pressure sensitive adhesive article comprising:
a pressure sensitive adhesive comprising:
a pressure sensitive composition; and
an additive, wherein the additive comprises a mixture comprising:
at least one copolymer comprising at least two repeat units of Formula I-b:

wherein:
each R 1 is independently an alkyl, haloalkyl, aralkyl, alkenyl, aryl, or aryl substituted with an alkyl, alkoxy, or halo;
each Y is independently an alkylene, aralkylene, or a combination thereof;
G is a divalent residue equal to a diamine of formula R 3 HN-G-NHR 3 minus the
two NHR 3 groups, wherein G is an alkylene, heteroalkylene, arylene, aralkylene,
or a combination thereof;
R 3 is hydrogen or alkyl or R 3 taken together with G and to the nitrogen to which they are both attached form a heterocyclic group;
n is independently an integer of 0 to 1500; and
p is an integer of 1 to 10; and
at least one thermoplastic organic polymer.

12. The article of claim 11 , wherein each R 1 of the copolymer is methyl.

13. The article of claim 11 , wherein each Y of the copolymer is an alkylene having 1 to 10 carbon atoms, phenylene bonded to an alkylene having 1 to 10 carbon atoms, or phenylene bonded to a first alkylene having 1 to 10 carbon atoms and to a second alkylene having 1 to 10 carbon atoms.

14. The article of claim 11 , wherein the copolymer has a first repeat unit where p is equal to 1 and a second repeat unit where p is at least 2.

15. The article of claim 11 , wherein n of the copolymer is at least 40.

16. The article of claim 11 , wherein the pressure sensitive adhesive article comprises a transfer tape.

17. The article of claim 16 , wherein the transfer tape is coated on a differential release liner.

18. The article of claim 11 , wherein the pressure sensitive adhesive is attached to a prepared or unprepared surface comprising a metal, a polyolefin film, or a fluorine containing polymeric film.

19. The article of claim 11 , wherein the pressure sensitive adhesive provides a protective coating to prevent ingress of contaminants to a bonded surface.

20. The article of claim 11 , where the pressure sensitive article comprises a pressure sensitive adhesive patch.
