摘要： A copolymer of a lactone and a polycyclic carbonate is prepared by heating a monomer of a lactone with a polycyclic carbonate having two cyclic structures including a carbonate group at elevated temperatures less than 200 degrees Centigrade in the presence of a catalyst. The described copolymers evidence excellent mechanical properties, good resorption velocity and do not disintegrate upon degradation into materials of high crystallinity.

摘要： Novel, rubbery copolymers of ethylene with at least one other .alpha.-alkene such as propylene, and a polyene such as 5-ethylidene norbornene-2, characterized by a differential scanning calorimetry thermogram maximum peak at a temperature between -7.degree. and +11.degree. C., are disclosed. These specific rubbery copolymers when one or more tackifiers are included therein, exhibit an unprecedentedly high tack and consequently provide for the first time EPDM-type compositions that have sufficient building tack for the manufacture of multi-ply articles such as tires.

摘要： Filament-like polymer crystal fibers are prepared from a solution of a crystallizable polymer, such as polyethylene or polypropylene, in a vessel containing a spinning rotor, preferably having a slightly roughened surface, according to the disclosed invention. The fiber thus formed is taken up and removed at a rate equal to the crystal growth rate. The longitudinal crystal growth rate is of sufficient speed for commercial application while at the same time yielding fibers of outstanding mechanical properties.
