Abstract

Polydiorganosiloxane polyamide, block copolymers having organic soft segments and methods of making the copolymers are provided.

First claim

We claim:

1. A film article comprising a copolymer, the copolymer comprising:
at least one repeat unit of Formula I-a:

and
at least one repeat unit of Formula VI-a:

wherein:
each R 1 is independently an alkyl, haloalkyl, aralkyl, alkenyl, aryl, or aryl substituted with an alkyl, alkoxy, or halo;
G is a residue having a valence of q;
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;
each Y is independently an alkylene, aralkylene, or a combination thereof;
each B is independently a covalent bond, an alkylene of 4-20 carbons, an aralkylene, an arylene, or a combination thereof;
D is an organic soft segment residue;
n is independently an integer of 0 to 1500;
p is an integer of 1 to 10; and
q is an integer greater than 2; wherein the film article comprises an unsupported film article.

2. The film article of claim 1 , wherein the copolymer comprises:
at least one repeat unit of Formula I-b:

and
at least one repeat unit of Formula VI-b:

3. The film article of claim 1 , wherein the copolymer is permeable.

4. The film article of claim 1 , wherein the film article is a multilayer film article.

5. The film article of claim 4 , wherein at least one layer of the multilayer film article comprises at least one layer of a conformable barrier material, a backing material, or a combination of these materials.

6. The multilayer article of claim 5 , wherein the backing material comprises an open structure backing.

7. A packaging composition comprising:
a copolymer, the copolymer comprising
at least one repeat unit of Formula I-a:

and
at least one repeat unit of Formula VI-a:

wherein:
each R 1 is independently an alkyl, haloalkyl, aralkyl, alkenyl, aryl, or aryl substituted with an alkyl, alkoxy, or halo;
G is a residue having a valence of q;
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;
each Y is independently an alkylene, aralkylene, or a combination thereof;
each B is independently a covalent bond, an alkylene of 4-20 carbons, an aralkylene, an arylene, or a combination thereof;
D is an organic soft segment residue;
n is independently an integer of 0 to 1500;
p is an integer of 1 to 10; and
q is an integer greater than 2; wherein the packaging composition comprises a composition for packaging electronic components.

8. The packaging composition of claim 7 , wherein the copolymer comprises:
at least one repeat unit of Formula I-b:

and
at least one repeat unit of Formula VI-b:

9. The packaging composition of claim 7 , wherein D comprises a polyether residue.

10. The packaging composition of claim 9 , wherein D comprises a polyoxypropylene residue.

11. The packaging composition of claim 10 , wherein the polyoxypropylene residue has an average molecular weight of from 450 to 8000.

12. A bodycare composition comprising:
an additive comprising a copolymer, the copolymer comprising
at least one repeat unit of Formula I-a:

and
at least one repeat unit of Formula VI-a:

wherein:
each R 1 is independently an alkyl, haloalkyl, aralkyl, alkenyl, aryl, or aryl substituted with an alkyl, alkoxy, or halo;
G is a residue having a valence of q;
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;
each Y is independently an alkylene, aralkylene, or a combination thereof;
each B is independently a covalent bond, an alkylene of 4-20 carbons, an aralkylene, an arylene, or a combination thereof;
D is an organic soft segment residue;
n is independently an integer of 0 to 1500;
p is an integer of 1 to 10; and
q is an integer greater than 2.

13. The bodycare composition of claim 12 , wherein the copolymer comprises:
at least one repeat unit of Formula I-b:

and
at least one repeat unit of Formula VI-b:

14. The bodycare composition of claim 12 , wherein D comprises a polyether residue.

15. The bodycare composition of claim 14 , wherein D comprises a polyoxypropylene residue.

16. The bodycare composition of claim 15 , wherein the polyoxypropylene residue has an average molecular weight of from 450 to 8000.

17. The bodycare composition of claim 12 , wherein at least 50 percent of the R 1 groups are methyl.

18. The bodycare composition of claim 12 , 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.

19. The bodycare composition of claim 12 , wherein n is at least 40.

20. The bodycare composition of claim 12 , wherein the additive comprises a fiber treatment to impart perfect smoothness, lubricity, a pleasant tactile sensation, or a combination thereof.

21. The bodycare composition of claim 12 , wherein the additive is a surface modifier, a slip aid, a compatibilizer, a refractive index modifier, an optics modifier, a rheology modifier, a permeability modifier, a water repellency modifier, or a combination thereof.
