Abstract
Polymers consisting essentially of the units (A) and (B) with an intrinsic viscosity in the range of 0.3 to 4.0, a content of the unit (A) of 10 to 90 mol % of the total structural units and a content of double bonds of trans-configuration of 40% or more are disclosed. The units (A) and (B) are represented by the structural formulas: ##STR1## wherein R' is hydrogen atom, an alkyl or phenyl, R.sup.2 is hydrogen or an alkyl, R.sup.3 is an alkyl. The polymers are preferably prepared by partial hydrolysis of the polymers consisting essentially of the unit (B).
