The disclosure generally relates to filaments and in particular, filaments for use in fused filament fabrication to prepare 3D printed articles. The filaments comprising a polymer composition, said polymer composition comprising: a) about 5 wt. % to about 60 wt. % of a thermoplastic polymer A having a melting peak temperature greater than 40&#xb0; C.; b) about 95 wt. % to about 40 wt. % of a thermoplastic polymer B having a melting peak temperature greater than 20&#xb0; C.; c) optionally from about 0.1 to 3 wt. % of a viscosity modifier; wherein: the melting peak temperature of thermoplastic polymer A is at least 20&#xb0; C. greater than the melting peak temperature of thermoplastic polymer B; thermoplastic polymer A is dispersed in thermoplastic polymer B; and the polymer composition has a melt index of at least 0.1 g/10 minutes using a 10 kg weight measured according to ASTM D1238-13 at a temperature which is less than the melting peak temperature of thermoplastic polymer A and which is greater than the melting peak temperature of thermoplastic polymer B.

Curing fluoroelastomers with curing agents of formulas (I), (II), (III), and (IV): wherein each of R, R, R, R, R, R, R, and R, is selected from the group consisting of H; halogen atom; C1 to C4 alkyl groups in which the alkyl group is linear, branched, or cyclic; OR'; and aromatic groups;

Curing agents for fluoroelastomers

A fluoroelastomer masterbatch comprising a particulate matrix material wherein the particles of the matrix material have an average size selected from the range of from 1 &#x3bc;m to 1000 &#x3bc;m in diameter, the concentration of fluoroelastomer is from about 0.2% to 40% by weight, and the fluoroelastomer is dispersed within the interstitial spaces of the particulate matrix material.

Olefinic interpolymer compositions comprising the olefinic interpolymer, residuals from a transition metal catalyst and boron containing activator package, and a charge dissipation modifier and methods for making them. The compositions have dissipation factors that are at least 50% less than the corresponding olefinic interpolymer compositions which have not been treated with charge dissipation modifiers. The compositions are useful in wire and cable applications.
