    摘要： An essentially isocyanate-free polyurethane, polyurea, polyethylenic oligomer is disclosed which is unusually strong and elastic and which possesses improved solvent solubility. This oligomer is the reaction product of: (1) organic diisocyanate; (2) a stoichiometric deficiency of difunctional materials reactive therewith and consisting essentially of: (A) diol component selected from polycarbonate diol and polyoxyalkylene glycol, this diol component having a molecular weight of from 200 to 2000; (B) dihydric bisphenol-based alkylene oxide adduct containing from 2-6 alkylene groups per molecule; and (C) a diprimary diamine component selected from alkylene diamine and polyoxyalkylene diamine, this diamine component having a molecular weight of from about 60 to 800. Components (A) and (B) are present in a mole ratio of, from 1:1.5 to 1:5 and component (C) is present to supply from 5 to 30 equivalent percent of the total equivalents of component (2). The polyurethane polyurea so-constituted is capped with monohydric ethylenic compound, such as 2-hydroxyethyl acrylate, to provide a molecular weight in the range of about 5,000 to about 30,000.This polyethylenic oligomer is cured by radiation exposure, as from an electron beam, and a polyethylenic cross-linking agent may be used to enhance the cure. The coating compositions are preferably pigmented and diluted to a resin solids content of about 5% to 15%, at which dilution they exhibit superior resistance to precipitation.

This oligomer is the reaction product of: (1) organic diisocyanate; (2) a stoichiometric deficiency of difunctional materials reactive therewith and consisting essentially of: (A) diol component selected from polycarbonate diol and polyoxyalkylene glycol, this diol component having a molecular weight of from 200 to 2000; (B) dihydric bisphenol-based alkylene oxide adduct containing from 2-10 alkylene groups per molecule; and (C) a diprimary diamine component selected from alkylene diamine and polyoxyalkylene diamine, this diamine component having a molecular weight of from about 70 to 800. Components (A) and (B) are present in a weight ratio of from 1:4 to 9:1 and component (C) is present to supply from 30 to 60 equivalent percent of the total equivalents of component (2). The polyurethane polyurea so-constituted is capped with monohydric ethylenic compound, such as 2-hydroxyethyl acrylate, to provide a molecular weight in the range of about 5,000 to about 30,000.This polyethylenic oligomer is cured by radiation exposure, such as an electron beam, using from 5% to 25%, based on total polymer solids, of a polyethylenic cross-linking agent.

    摘要： A wheelchair which can negotiate curbs and other obstructions with a minimum of effort by the wheelchair occupant. The wheelchair has conventional front caster wheels and rear propulsion wheels, with first auxiliary support wheels located between the caster and rear wheels, and second auxiliary wheels being located outboard behind the rear wheels. The castered wheels and the rear wheels are structured to be raised or lowered by the wheelchair occupant. When a curb is encountered, the occupant propels the wheelchair forwardly until the first auxiliary wheels are at the edge of the curb, and the castered wheels are suspended. The castered wheels are then lowered to the bottom of the curb and the wheelchair propelled forward until the second auxiliary wheels are at the curb edge. The large rear wheels are then lowered to curb level, and the wheelchair is propelled by the occupant to the opposite curb, where the curb is ascended by turning the wheelchair 180.degree. and performing the wheel adjusting process in the opposite sequence.
