Where non-chemist could find such info, for example? I need to understand the angles at which these monomers connect with each other. Appreciate any insights,

The polymer backbone is made up of relatively unstrained, unhindered sp3 hybridized carbons, so the bond angles will be pretty close to that of other tetrahedrally coordinated centers (~109.5 degrees or so).

Thank you very much for your attention. Please look to my schematics: do I understand correctly: if we say that red X axis goes along the monomer, so they will connect approx ~110 degrees. However, of course, the monomer unit may freely rotate around Y and Z axis and get any kind of angle ( in the schematics both rotations Y and Z is equal to zero). Do I get this right?

Each carbon will be at the apex of a roughly 110-degree angle, and there are two (backbone) carbons in each monomer. You might want to take a look at some basic physical models of polymers, starting with the ideal chain model:

Polymer physics is quite a bit more complicated than this, but it’ll get you started.
