1. A compound of formula I
 where
R is hydrogen or methyl,
G1 and G2 are independently alkyl of 1 to 4 carbon atoms or are together pentamethylene,
x, y and z are each independently greater than or equal to 1,
L is independently of each other a direct bond or a hydrocarbylene group,
Z1 is hydrogen or hydrocarbyl, or is —OR1, —OCOR1, —COOR1, —CONR1R2, —NR1COR2, —COR1 or —NR1R2,
R1 and R2 are independently of each other hydrogen or hydrocarbyl, or R1 and R2 together form a hydrocarbylene group,
E is oxyl, hydroxyl, alkoxy, cycloalkoxy, aralkoxy, aryloxy, —O—CO—OG, —O—Si(G)3, or —O—CH2—OG where G is selected from the group consisting of hydrogen, an aliphatic, araliphatic and aromatic moiety; or E is —O-T-(OH)b,
T is a straight or branched chain alkylene of 1 to 18 carbon atoms, cycloalkylene of 5 to 18 carbon atoms, cycloalkenylene
of 5 to 18 carbon atoms, a straight or branched chain alkylene of 1 to 4 carbon atoms substituted by phenyl or by phenyl substituted
by one or two alkyl groups of 1 to 4 carbon atoms,
b is 1, 2 or 3 with the proviso that b cannot exceed the number of carbon atoms in T, and when b is 2 or 3, each hydroxyl
group is attached to a different carbon atoms of T, and
FRM is independently of each other a flame retardant moiety selected from the group consisting of
 wherein T1 and T2 are independently alkyl, aryl, alkoxy, aralkoxy or dialkylamino; or said alkyl, aryl, alkoxy, aralkoxy or dialkylamino substituted
by 1 to 8 halogen atoms;
 where one of the open bonds may be bonded to T1, defined above;
 where one of the open bonds may be bonded to T1, defined above;
 where one to three of the open bonds may be bonded to T1, defined above;
 where one to three of the open bonds may be bonded to T1, defined above;
 where one to three of the open bonds may be bonded to T1, defined above;
