Abstract
A composition comprising a blend of polypropylene with the reaction product of a functionalized polypropylene and an amidoamine is disclosed. The composition may be produced by combining polypropylene, functionalized polypropylene and an amidoamine in an extruder, and may also include an elastomer or other additives.
Claims29
A composition useful for the preparation of molded articles comprising polypropylene and the reaction product of a functionalized polypropylene and an amidoamine, wherein the amidoamine has the formula:
- ##STR18## wherein:
- A=B or D, and
- B=R--O--(R'O).sub.x -- ##STR19## R is an alkyl of 1 carbon when A=B;
- R' is an alkyl of 2 carbons when A=B;
- R is a straight or branched alkyl of 0 to 3 carbon atoms when A=D;
- R' is an alkyl group of 0 or 2 carbon atoms when A=D;
- R" is a branched alkyl group of 3 carbon atoms;
- R'" is a branched alkyl group of 3 carbon atoms;
- a is independently 1 to 200;
- x is independently 1 to 200
- y is independently 1 to 300;
- and
- p is independently 2 to 11.
A process for making a composition, comprising:
- compounding polypropylene, a functionalized polypropylene and an amidoamine, such that the functionalized polypropylene and the amidoamine form a reaction product, wherein the amidoamine has the formula:
- ##STR20## wherein:
- A=B or D, and
- B=R--O--(R'O).sub.x -- ##STR21## R is an alkyl of 1 carbon when A=B;
- R' is an alkyl of 2 carbons when A=B;
- R is a straight or branched alkyl of 0 to 3 carbon atoms when A=D;
- R' is an alkyl group of 0 or 2 carbon atoms when A=D;
- R" is a branched alkyl group of 3 carbon atoms;
- R'" is a branched alkyl group of 3 carbon atoms;
- a is independently 1 to 200:
- x is independently 1 to 200
- y is independently 1 to 300;
- and
- p is independently 2 to 11.
