A rheology system includes a rheometer including a lower plate and an upper plate, a manipulator including an arm, a loading end effector, a cleaning end effector, and a controller communicatively coupled to the rheometer and the manipulator, the controller including a processor and a computer readable and executable instruction set, which when executed, causes the processor to direct the manipulator to couple the loading end effector to the arm, direct the manipulator engage a specimen with the loading end effector, direct the manipulator to position the specimen on the lower plate of the rheometer, direct the upper plate to engage the specimen between the upper plate and the lower plate, direct the manipulator to couple the cleaning end effector to the arm, and direct the manipulator to engage the lower plate with the cleaning end effector.

A resin including up to 99.99 weight percent (wt. %) of a first polyolefin grafted with a functional group selected from an ethylenically unsaturated carboxylic acid, a carboxylic acid anhydride, an ester functional group or a combination thereof; and 0.01 to 3.0 wt. % of a tin oxide-based catalyst, where the resin includes 0.2 wt. % to 1.5 wt. % of the functional group from the first polyolefin, the wt. % based on a total weight of the resin. The first polyolefin can be selected from a polyethylene, a polypropylene, an ethylene/alpha-olefin copolymer, a propylene/alpha-olefin copolymer and combinations thereof. The tin oxide-based catalyst can be selected from dibutyltin oxide, dioctyltin oxide and combinations thereof. The resin can be used in a multilayer structure, where a Layer A comprises the resin and a Layer B comprises a polyester, where a first major surface of Layer A is in adhering contact with the second major surface of Layer B.
