Disclosed are non-woven fabrics made from fibers formed from melt-processable and stable addition copolymers containing 30 to 90 weight percent acrylonitrile moiety and up to 70 weight percent methacrylonitrile moiety and optionally less than 20 weight percent moieties of other comonomers.

Nonwoven fabrics from high nitrile copolymers

A process for improving the processability of polycarbonates by contacting a polycarbonate composition with a metal salt of dodecylbenzenesulfonic acid in an amount sufficient to decrease the melt viscosity of the polycarbonate composition while increasing the impact strength.

Metal dodecylbenzenesulfonates as processing aids for polycarbonates

It has been found that the addition of small amounts of a benzoate or acetate ester of a polyfunctional hydroxy-containing compound to a maleic anhydride-containing resin greatly increases the flowability and processibility of these resins.

Esters as processing aids for maleic anhydride resins

It has been found that the addition of small amounts of a benzoate or acetate ester of a polyfunctional hydroxy containing compound to an olefinic nitrile copolymer composition greatly increases the flowability and processibility of these thermoplastic copolymers.

Esters as processing aids for olefinic nitrile copolymers

Impact-resistant polymers having excellent color, clarity and low permeability to gases and vapors are prepared by polymerizing in a specified manner an olefinically unsaturated nitrile such as acrylonitrile, an ester of an olefinic acid such as methyl acrylate, or a vinyl ester such as vinyl acetate, and a vinyl aromatic monomer such as styrene optionally in the presence of a diene rubber.

Nitrile barrier resins and process for their manufacture

A method for stripping residual monomer from acrylonitrile copolymers which have been prepared in aqueous suspension by steam stripping acrylonitrile monomer from the suspension at a temperature of from 100.degree. C. up to 135.degree. C. and at a pressure of from about 5 to 30 psig is described.

Rapid removal of residual monomers from acrylonitrile copolymers

Acrylonitrile copolymers having controlled molecular weight are prepared using terpinolene or gamma terpinene as chain length modifier.

Process of polymerizing acrylonitrile copolymers employing terpinolene

Acrylonitrile copolymers having controlled molecular weight are prepared using a synergistic mixture of mercaptan and certain hydrocarbons as chain transfer agent.

Mercaptan-hydrocarbon chain modifiers in acrylonitrile copolymers

The present invention relates to a method for stabilizing thermoplastic nitrile resins against thermal discoloration by the inclusion in the resins of the reaction product of maleic anhydride and polyvinyl alcohol in amounts of from 0.1 to 1.5 parts by weight per 100 parts of resin.
