摘要： The present invention provides methods of using a novel sulfonated resin catalyst, showing improved performance. The catalyst has reduced or partial functionalization, throughout the sulfonated region of the polymer, leading to reduced by-product formation and other desirable features. This catalyst has particular usefulness in reactions or processes sensitive to high acidity, e.g., esterification-transesterification.

摘要： A portable trash bag opener is an apparatus that is used to hold open the rim of a trash bag while a user disposes items into the trash bag. The apparatus includes a hoop, a first arc-shaped wing, a second arc-shaped wing, and a handle. The hoop is used to internally brace the rim of the trash bag. The first arc-shaped wing and the second arc-shaped wing are used to externally clamp the rim of the trash bag against the hoop. The first arc-shaped wing and the second-arc shaped wing are positioned opposite to each other about the hoop. The handle allows the user to easily grasp the apparatus with one of their hands.

摘要： The present invention provides a macroporous copolymer having large pores, typically in the range of 5,000-200,000 Å and a typical breaking weight of at least 175 g/bead. The macroporous copolymers can be made using an interpenetrating polymer network (IPN) techniques. These macroporous copolymers may also form macroporous resins. The present invention also provides methods of using the macroporous copolymers and resins.

摘要： Hydroquinonoid polymers having n recurring units of the General Structural Formula ##STR1## wherein n is 3 or greater, X and X' independently are hydrogen or methyl, R is a lower hydrocarbon, and R' and R" independently are lower hydrocarbons or hydrogens are disclosed as well as such polymers additionally containing phenolic copolymerizates. The preparation of these polymers by the one step copolymerization of a diolefinic hydrocarbon, a hydroquinonoid and optionally a phenolic, in the presence of an ortho-alkylation catalyst, and the use of these polymers as antioxidants, especially for foodstuffs, is also disclosed.
