Polyolefin interpenetrated network material for hydrocarbon recovery

A polyolefin interpenetrated network comprising a soft polyolefin network and a rigid polyolefin network, which is either an amorphous polyolefin network with a Tg of at least 50° C. or a semi-crystalline polyolefin with a Tm of no less than 35° C., wherein the soft polyolefin network is represented by formula (I)

• wherein (CH2—CH(R)) represents the same or different olefin repeating unit;
• R is independently H or a C1-C28 linear, branched, or cyclic alkyl moiety;
• n is an integer greater than about 500;
• (CH2—CH(Ar)) represents the same or different aromatic repeating unit;
• Ar is an aryl moiety that can be substituted with one or more R1 groups;
• wherein R1 is a C1 to C10 linear, branched, or cyclic alkyl moiety that can be substituted with one or more C1 to C5 alkyl groups;
• p is an integer in the range from 0 to 15,000;
• R2 is either present or absent and when R2 is present, R2 is a C1 to C10 linear, branched, or cyclic alkyl moiety that can be substituted with one or more C1 to C5 alkyl groups;
• X is a cross-linking moiety resulting;
• and q is an integer greater than about 5.
