Blends of 5 to 97.5% of a segmented thermoplastic copolyester such as polybutylene terephthalate containing polybutane glycol segments with 95 to 20% of a blend of an ethylene copolymer and 5 to 75% either polyvinyl chloride or polyvinylidene chloride. The polyethylene copolymer is an elastomeric blend of polyvinyl chloride or polyvinylidene chloride with a copolymer of ethylene and esters of ethylenically unsaturated acids, vinyl esters, vinyl alkyl ethers, vinyl chloride, vinylidene chloride a...

Polyamide and poly(ester-amide) materials are melt-blended to give products having good flexibility at high and low temperatures. The blends are useful for potting, encapsulating, and adhesive applications.

Homogeneous blends are provided comprising a diblock copolymer of isoprene and butadiene and a homopolymer constituent which is polyisoprene, polybutadiene or mixtures of polyisoprene and polybutadiene.

Disclosed are novel blends of peroxides that are liquid at room temperature. Blend (1) consists essentially of dicumyl peroxide and cumyl isopropylcumyl peroxide and blend (2) consists essentially of bis(alpha-t-butylperoxyisopropyl) benzene and isopropylcumyl t-butyl peroxide. The blends are useful in crosslinking polymers such as polyethylene.

Blends of a copolymer of methyl methacrylate and styrene with an acrylonitrile-styrene copolymer have improved optical, mechanical and gas barrier properties as well as improved processability.

A blend including phytosterol together with saturated fatty acids and/or saturated fatty alcohols is disclosed.

Polymers containing a high percentage of vinyl alcohol units may be blended with copolymers of alkyl methacrylates and unsaturated organic acids and processed into sheet, film, fiber and other objects which exhibit an useful balance of barrier and strength properties.

Polymers containing a high percentage of vinyl alcohol units may be blended with copolymers of alkyl methacrylates and unsaturated organic acids and processed into sheet, film, fiber and other objects which exhibit an useful balance of barrier and strength properties.

Polymer blends of at least one polar polymer are prepared by admixture with a poly(vinyl alcohol) and a (meth)acrylate copolymer also containing vinyl amide and/or unsaturated acid units. The ternary compositions have attractive processing and performance properties.

Thermoplastic blends comprising mixtures of dissimilar plastics and dissimilar rubbers are described; they are improved by incorporation of functionalized olefin polymer.
