Abstract
Abstract Novel methods are described for providing filled thermoplastic polymers by the integral addition, to the polymer/filler mixture, of a surfactant with or without a polymerizable unsaturated silicon compound containing at least one =SiO-group and not more than five silicon atoms, e.g., a polymerizable unsaturated hydrolyzable silane, and/or a polymerizable unsaturated organic compound having two or more polymerizable unsaturated groups and novel filler/polymer compositions containing a surfactant are described. In addition novel integral additives containing surfactant and a polymerizable unsaturated silicon compound containing at least one =SiO-group and not more than five silicon atoms, e.g., a polymerizable unsaturated hydrolyzable silane, and/or a polymerizable unsaturated organic compound having two or more polymerizable unsaturated groups are described.

An integral additive for improving the physical properties of thermoplastic organic polymer filled with inorganic fillers comprising a mixture of (1) a polymerizable unsaturated silicon compound having one to five silicon atoms interconnected by ≡SiOSi≡ linkages when said compound contains more than one silicon atom per molecule, contains at least one silicon-bonded vinyl-polymerizable unsaturated group, and contains at least one silicon-bonded hydrolyzable group when said compound contains one silicon atom per molecule and wherein any valences of silicon not satisfied by oxygen of the ≡SiOSi≡ linkage, by a silicon-bonded hydrolyzable group or by a silicon-bonded vinyl polymerizable unsaturated group are satisfied by a monovalent hydrocarbon group free of vinyl-polymerizable unsaturation, and/or a polymerizable unsaturated organic compound having at least two polymerizable unsaturated groups and (2) a surfactant comprising: (a) a siloxane containing at least one silicon-bonded alkyl group having at least 12 carbon atoms.
Claim 2
Dependent Claim
144 words
An integral additive for improving the physical properties of thermoplastic organic polymer filled with inorganic fillers comprising a mixture of (1) a polymerizable unsaturated silicon compound having one to five silicon atoms interconnected by ≡SiOSi≡ linkages when said compound contains more than one silicon atom per molecule, contains at least one silicon-bonded vinyl-polymerizable unsaturated group, and contains at least one silicon-bonded hydrolyzable group when said compound contains one silicon atom per molecule and wherein any valences of silicon not satisfied by oxygen of the ≡SiOSi≡ linkage, by a silicon-bonded hydrolyzable group or by a silicon-bonded vinyl polymerizable unsaturated group are satisfied by a monovalent hydrocarbon group free of vinyl-polymerizable unsaturation, and/or a polymerizable unsaturated organic compound having at least two polymerizable unsaturated groups and (2) a surfactant comprising: (a) a siloxane containing at least one silicon-bonded alkyl group having at least 12 carbon atoms.
