Abstract: Compositions having high notched Izod impact strength and Gardner VHIT impact value are achieved by blending polyglutarimides, multiple stage polymers based on butadiene or acrylates, and polycarbonate in a weight ratio such that the polycarbonate comprises about 12 to 25% of the blend.

Abstract: Polyolefins are rendered resistant to degradation upon exposure to heat by incorporating therein a stabilizing amount of a synergistic combination of a phenol-terpene resin, a sulfur-containing secondary antioxidant and a phosphonitrilic composition derived rom a phosphonitrilic halide and certain hydroxy compounds. The above synergistic combination is especially effective for stabilizing polyolefins containing carbon black.

Abstract: 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 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 EDPM-type compositions that have sufficient building tack for the manufacture of multi-ply articles such as tires.

Abstract: A process for the preparation of a modified hydrocarbon resin suitable for use as a binder in a printing ink from a hydrocarbon resin (I) relatively unsuitable for use as a binder in a printing ink and having a melting point of at most 110.degree. C. which comprises reacting in at least one step and in any desired sequence (I) as defined below with (II) approximately 3-20% as much by weight of a dicarboxylic acid unit as defined below and with (III) approximately 1-100% as much by weight of an alkyl phenol-aldehyde resin or its equivalent as defined belowwherein(I) is a hydrocarbon resin containing at most 20% by weight of indene or methyl indene units and is based on a considerable proportion of polymerizable hydrocarbon monomers containing about 5 to 11 carbon atoms and at most 20% by weight of indene or methyl indene(II) is selected from the group consisting of(IIa) an .alpha., .beta.
