Abstract
Various embodiments described herein are directed to a polymer composition comprising polyethylene and a reaction product of the copolymerization of the ethylene and (meth)acrylic ester functionalized polysiloxane, and optionally one or more units derived from a termonomer. Articles made from the polymer composition and methods of making the polymer composition are also described.
Claims18
A polymer composition comprising polyethylene and a reaction product of the copolymerization of ethylene monomer and (meth) acrylic ester functionalized polysiloxane, and optionally one or more units derived from a termonomer, wherein the (meth) acrylic ester functionalized polysiloxane has a structural formula of one or more of the following:
- where:
- R is methyl or hydrogen;
- R1 is a bridge group that connects functional group (meth) acrylate with siloxane selected from the group consisting of a C2-C20 alkylene linker where one or more carbon atoms can be substituted with oxygen and silicon;
- R2 is an end group selected from alkyl, aryl, or alkenyl;
- x is an integer from 10 to 1000;
- and y is an integer from 1 to 20.
A process comprising:
- reacting, in a polymerization reactor under free-radical polymerization conditions and at a pressure greater than or equal to 100 MPa, ethylene monomer and a (meth) acrylate ester functionalized polysiloxane to produce polyethylene and a copolymer comprising low density polyethylene (LDPE) and functionalized polydimethylsiloxane (PDMS), wherein the (meth) acrylic ester functionalized polysiloxane has a structural formula of one or more of the following:
- where:
- R is methyl or hydrogen;
- R1 is a bridge group that connects functional group (meth)acrylate with siloxane selected from the group consisting of a C2-C20 alkylene linker where one or more carbon atoms can be substituted with oxygen and silicon;
- R2 is an end group selected from alkyl, aryl, or alkenyl;
- x is an integer from 10 to 1000;
- and y is an integer from 1 to 20.
