摘要:
Polymer particles in a size range between 2 and 15 micrometers, and having a refractive index close to, but not identical with, that of a matrix polymer and optionally having one or more enclosing shells, the outer shell being compatible with the matrix polymer, impart light-diffusing properties to the matrix polymer without degrading its physical properties, while the particles having a closer refractive index match to the matrix polymer impart gloss reduction to the surface of the matrix polymer.

摘要:
Polymers containing a high percentage of vinyl alcohol units, especially when treated to remove impurities, when blended with copolymers of alkyl (meth)acrylates, N-vinyllactams or N-vinylamides, and unsaturated acids, preferably further with a small amount of plasticizer, may be applied as hot melt adhesives to paper, wood, and other cellulosic articles.
摘要:
A polymer blend of a polyglutarimide and liquid crystalline copolyester polymer or benzimidazole polymer. The blend is a melt-compoundable polymer blend.

摘要:
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.
